Oh definitely. 27 here, high school is when I lost the most.

Sophomore year, my grandparents were murdered
8 months later my best friend hung himself
5 months later a long time friend died in a car accident in front of me [and our entire school bus that he was supposed to be on that day]
1 year and 1 month later a friend that helped me through those deaths also died in a car accident
1 year and some months later my step-grandmother, the only paternal grandparent I ever new, died and we weren't told about it. Found out on FB
That same year a friend I met freshman year killed herself after coming home from a trip to Greece
Two years later another friend killed himself, leaving a wife and kid behind

And in the years since then, I've lost two beloved cats, and helped my sister and step-daughter get through the loss of their own friends. My husband, bless his heart, is one such person you mentioned that has NEVER dealt with suicide, or death as a young person. He's 44 now, and was at a loss of what to do to help our daughter.

He doesn't say it often, because it is kind of a morbid sentiment, but it's one I share with him: We're grateful that I have the experience I do in death, because I was able to help her. And my kid-sister, too, they're both lost about what to do and how to heal.

I was quite taken aback when my husband said he had NEVER had anyone die like that; Suicide, or even just young. I couldn't fathom how that wasn't... NORMAL.
