Well, pray that you don't!
There's one girl in my YG who's allergic to everything, has anxiety problems, and a weak immune system, plus probably one or two things I don't know about. I have another friend who moved away earlier this year who's also allergic to everything, has a terrible immune system, has asthma, has Vocal Cord Dysfunction, and is constantly hurting herself. Her sister isn't much better, aside the breathing issues.
