I usually feel like there's a heavy load on my chest that makes me have to forcefully breathe. Its kinda annoying, especially that it occurs during sleep, when I am lying in bed, that is. I also have problems with extrasystole (skipped beat), and its really bothering me because I'm only 16.
My parents are doctors and they tell me I'm fine, but I think that they're taking it for granted.
Does anyone suffer from similar problems? And is this related to me being an INFP, or is it some other thing, like caffeine or stress?
