does any one else throw up when theyre upset?

I feel like it to the extreme but i never actually do. Its good though that your body knows how to relieve stress just dont self inflict it and go all anorexic and stuff

No BUT, your better off. When I get really stressed my whole body goes limp. I can ba30rley talk and have to lie down before I pass out. Some peoples bodies have a strange way with dealing with stress but is nothing serious. Meds can help if this happens often and DR's are usually very willing to write a script. If your older have a stress test to make sure your heart is not being damaged by stress, if your under 35ish - see a dr but dont worry.

I don't but sometimes people believe it makes you happier because they believe it relieves you of stress but really it's just acid from your stomach but its not abnormal.

I don't myself, but I know that happens to some people when they get really worked up. I don't think it's abnormal.
