I'm sorry you feel this way But if you don't keep trying then you'll be stuck in your misery anyway. So I think it's better to try and change something. What's the point of being in a relationship with someone who doesn't care much and neither do you?
Have you tried maybe refreshing some old contacts, with old friends?
With online dating I'd keep trying, maybe something will finally help you. I imagine it's frustrating and infuriating. One thing you cannot do is give up on yourself. I know how it feels to be closed in your own bubble, because I'm the same (was lucky to meet bf in high school but if that didn't happen I'd still be single and probably as miserable as you are, studies didn't help me make new friends, although that's on me, I was too shy). Maybe try to get out of your comfort zone a little bit to meet someone. I know it's hard, especially with additional issues like bipolar.
For example, if I'd be single, I'd probably try to go on that voice-acting course I want to take. That's a chance to meet someone. Do you have anything like that, that would allow you to meet someone? Or maybe there is some club you could join? Or at least a group on social media?

I Know But...Trying So Hard,For So Many Years Just Takes So Much Out Of You And I'm The Kind That Get's Easily Discouraged If Something Seems Like It Won't Work. Trying To Reconnect With People Won't Do Me Any Good,Since I've Totally Lost All Contact With Most Of Them And The One's I DO Still Have A Way To Contact Have Ether Totally Moved On With Their Lives Or Made It Pretty Clear That They Value Their Other Friends More Then Me (Something I'm A Little Too Emotionally Unstable To Handle) So In Ether Case,Trying To Reconnect With Them Would Likely Just Be A Waste Of Time And Energy. I Don't Have Any Clubs Or Anything I Can Join, Ether Since I'm 26 And Don't Go To Collage And Even If I DID I'd Likely End Up Just Sitting There,Alone While Wondering Why I'm Even Bothering To Go There In The First Place (Like I Have In MANY Other Cases) And What's Worse Then Being Alone,Is Being Alone Around Other People. In All Honesty,I Kind Of Just Wish I Could Just Close Myself Off From Reality All Together And Create My Own Where I Am Free From All Of This. Hell,Back In Middle And High School I Kinda Had A Mini Mental Breakdown Where I STARTED By Playing Pretend,But That Quickly Turned Into Flat Out Thinking I Was Able To Pull The Spirits Of Anime/Cartoon Characters From Their Worlds,To THIS One. All My Interactions Felt So Real And...Invested That Even To This Day I Can't Tell If It Was Just A Mental Breakdown Or If I Was Really Tapping Into Some Kind Of Magick That I Can't Access,Anymore. Whatever The Case May Be,It's Clear That It Was A MUCH Needed Defence Against The Hell I Was Forced To Endure And God Knows What Would Have Happened If I DID'T Have It. At Least I Was A Tiny Bit Happier,Living In My Own Little Pocket Of Reality (Even If It Was Not Without It's Share Of Pain. Not Even My Own Mind Will Allow Me Pure Bliss). Honestly,I've Been Looking For Ways I Could Just Insert A Majority Of My Existence Into The Internet. Take On A Totally Different Persona And Just Live A Totally Different Life,Without Having To Deal With THIS One (Minus Food And Going To The Bathroom). Hell,Even Just A Game Or Something That I Could Get So Hardcore Into That I Can Escape Everything THAT Way,Would Be Nice (Though Sadly I've Yet To Find Anything I Can Get That Into). All And All I Just Want OUT. If I Could Just Turn It All Off And Try Again,I Would In A Heartbeat. Sadly,I Don't Think Technology Is Quite There Yet And I Don't Have It In Me To Commit Suicide So That Just Kinda Leaves Me Stuck. Oh,Btw I Have Borderline Personality Disorder,Not Bipolar Disorder. Two Very Different Disorders. Just Feel I Should Clear That Up.

Then you're looking for an addiction. And I won't say it's a good idea. Better go to some therapy You're clearly depressed and can't really handle what's going on, so maybe a professional could help you out.
Oh, sorry for messing up the disorders, I am aware they're different, I guess I just read wrong

It's Fine. Just Wanted To Clear It Up,Since It's A Whole Other Can Of Worms.>_< As For Therapy,It's True That I Need It (Pretty Badly At That),But I've Tried It Before (Twice) And Was't Able To Get Anywhere Due To The Fact I Don't Really Trust One Enough To Tell Anything To (Yes,I'm Talking About It All Here But There Is A Big Difference Between This And Being Face To Face With Someone That I Know Is Judging Me And Likely Gonna Write Down A Bunch Of Things That They THINK Is Going On But It's Not. At Least Not How They Think It Is). I've Resorted To "Self-Esteem Training" At The Local Gym,But My Doubts Are Pretty High That It Will Do Any Good. So Far,I Think Just Talking It Out With Someone Like This (That's Not Me) Is The Best Is Can Do. At Least It Get's It All Out.

Oh, I get it, it's hard to find a therapist you're compatible with. Something you must know is that a therapist isn't there to judge you, but to support you and help you with sorting out what's going on. About half a year ago I finished my own therapy, my goal was my self-esteem. And I told my therapist that I'm not sure how much I will trust him and that I am afraid of being judged by him. He completely understood but assured me his job is not to judge but to help.

Whatever bothers you with a therapist, the best solution is to tell him/her. Then they get a clear message from you, that you dislike their approach or that you're particularly worried about something. And if you two don't click, change a therapist.

Do therapists always write down things, where you live? Only once have I had such a therapist and it didn't feel okay to me too. She wasn't very helpful either and she was trying to convince me about how I feel instead of actually listening to what I'm saying. Anyways, a therapist who just talks with you is much better, it's like merely having a conversation.
I think it's still worth a try. You can make an appointment with a therapist and just tell them at the very beginning you're afraid of the judgement. Maybe then you could kick it off, I'm sure they'd know how to behave then.

I'm glad you at least talk things out here, it's something

What is this self-esteem training at your gym?

Ya,Therapists Here Write Things Down. I REALLY Don't Like It,Cause I Just Know They Are Writing Down A Bunch Of Disorders I May Or May Not Even Have (It Would't Be The First Time. When I Was Little,I Was Told I'm Right On The Edge Of Having A "Learning Disability". Problem Is,I'm SMART. Like REALLY Smart. The Gym Trainer Said So And So Will ANY Of My Online Friends. But Because Some Moron With A Piece Of Paper Said Otherwise,I Then Was Forced To Be In A "Modified Program" From Grade 2 All The Way Until I Graduated And It REALLY Screwed Up My School And Even Social Life. Point Is Just Because Some "Pro" Says It,Does't Make It True). Plus I Know It's Not Their JOB To Judge,But They Are Still Human. They May Not Ever Be Allowed To ADMIT It,But I'll Bet Anything That They Still Do It. It's Just Not Out Loud. As For The "Self-Esteem Training" At The Gym,I Have No Idea. I Just Went There To Slim Down A Little So I Have A More Cat-Like Form For My Cat Fursuit I Intend To Buy,But Then He Brought Up The Self-Esteem Training And I Already Kinda Let My Self Hate Slip Out,So He Kinda Insisted I Try It Out So I Was Just Like "Sure,Whatever". I Don't See Much Coming Out Of It,Though. My Guess Is That They Are Used To Things Like "I'm To Big/Small And I Hate Myself Because Of It". That's All Well And Good,But My Issues Are A WEE Bit More Deeply Rooted Then A Simple Self Image Problem. I Kinda Doubt Personal Gym Trainers Are Ready To Handle Something Like Me.^^'

Well, yeah, therapists are still human but they should stay impartial if they want to properly do their job. They usually don't like to think about their clients outside of their office, at least I wouldn't want to. That would mean I can't differ my personal life from my professional life and every therapist will know it's not a very healthy thing to be doing.
Besides, it's also not good to care about what other people think about you. What you think about yourself is much more important. And what the people you care about think. It's like with being smart. And if you feel awfully judged by a therapist, at least it's not your relative so you can look for another one.
And even if you care about other people's judgement, isn't it also possible that I'm judging you? I'm not a professional, I'm not trained to not judge and to focus on the psychological aspects of the conversation. I don't think it's much safer to chat on the forum than speaking to a professional :)
I don't mean you shouldn't chat, just had a thought

I still think it's nice that they have such a program, means they care about people and don't just go "sport, sport, sport because being smart is for eggheads" Maybe at least it will work in the body image aspect for you, that would still be great

True,But Still. And I Still Feel Safer Talking About It Here,Because At Least I Can Tell You Off If You Turn Out To Be A Bitch (Not That You Would. I'm Just Saying That It's Nice Having That Power).XD Can't Really Do That With A Therapist (I'd Be Locked Up In The Nut House For SURE,With The Way I Tell People Off. That Or Prison). So Ya,Point Is I Feel Safer Doing It Here Because At Least I Can Deal With The Judgment. I'm The Kind Of Person That Will Do Something,DESPITE The Judgement But Won't Take Any Of Your Crap Ether: Family Or Not,If You Got A Problem With Me Then Get The Hell Out Of My Life. I Don't Have Any Real Connection Or Attachment To ANYONE In My Family,So If One Was To Decide They Did't Like What I Was Doing Or Something Then I Have No Problem Dropping What Little They Have To Do With My Life. As For The Gym,I Told Denis (My Trainer) That I'd Give It A Shot So We'll See What's What Once I Get Started On It. Body Image In Not Really A Issue Though (I'm Not HUGE Or Anything. I Just Gained A Bit More Pounds Then Would Work Well With My Fursuit,So I'm Trying To Get Back Closer To What I Was Before The Pounds). That Being Said,I'm Not What You'd Call "Happy In My Own Skin" Ether,But That's A WHOLE Other Can Of Worms To Deal With. It's Kinda Complex.>_<

Ah, I get it. I think it feels safer here because there's no actual contact, just chat, so there's less things to get worried about, like strange looks and significant sighs etc. It's easier to deal with just words, you can just log out or don't look into the particular thread anymore.
Well, there are ways to tell someone off politely XD Like "sorry, I don't think this is working out for me, I think I'll try to find someone else to talk to".

Hehe, I get you with body image. I gained a belly sometime ago and few months ago I began hating myself a bit so I began working out at home and now I feel decent. But it's just decent ;P lol

I Don't Do Polite,When I'm Angry: I Do "Savage Animal About To Rip Your Limbs Off".XD But Ya,It's A Lot Easier To Talk When It's JUST Words That I Gotta Deal With (As You May Have Guessed By Now,I'm Not Much Good At Social Interaction). And Ya,I Legit Just Have A Few Pounds To Get Rid Of So It's Just A Matter Of Getting Them Down Enough So My Figure Matches My Fursona's (I'm REALLY Picky About That Kind Of Stuff). Also Don't Be Too Hard On Yourself About A Few Extra Pounds: I Had A Girlfriend/Friend (Who Died While Seeing Family In Brazil So That Kinda Sucks) That Thought She Was Flat Out Fat,When In Reality She Was Just A Little Plump And It Was A Cute Kind Of Plump. Don't Get Me Wrong,It's Good To Be Healthy. But People Are Much Too Black And White About It,When In Reality There Are Many Levels Between Being FAT And Just Being A Little Plump (And Even Then,You Can Be Fat And Still Look Good: There Is Fat And Then There Is GROSSLY Fat. Grossly Fat Being What You'd See On TV,Where Someone Is So Big That They Can't Even Move On Their Own. Most People Are Not That Fat). From The Sound Of It,You're Just A Little Plump So Don't Beat Yourself Up Over It. I'm Sure You're Way Prettier Then You Give Yourself Credit For.^^
