Lol, I'm similar XD
It's just stomach is very easily influenced by stress, and I'm a ball of stress

So I've been stressing so much that my stomach began acting up, by producing too much acid and that causes nausea and all that kind of ugly stuff.
About allergies tho, I think I have some but I'm not diagnosed. I know I wasn't born with them for sure
Maybe that's it, though cucumber soup is much more acidic XD
Nah, I don't. I've many fears and phobias, so I avoid travelling XD' So it's a huge stress if I go to a completely new place I've never been to, and alone.
