So I feel like i’ve been experiencing this on and off for the past few months. At first i’d notice it would happen if I was feeling down or around my period. I feel really weak and out of breath and get a sharp pain in my left arm when i breathe in and sometimes it feels a bit numb, but heart rate stays normal. But recently it’s been happening when I feel mentally fine and when i’m not anxious about anything. I’ve also noticed it only ever happens when I’m alone in my room not doing much, this has never happened to me when i’ve been out and about. That’s why i’m trying to tell myself it’s just anxiety but it’ll catch me off guard when just in my room. And then it goes away and comes back, I know thinking about it makes the anxiety worse but could this even be anxiety related in the first place? I don’t really get anxious anymore apart from when this happens. I feel like i can’t take a deep breath and this sometimes lasts for days and then i’m fine again. I also feel like im gonna pass out but ive never passed out before. I’m still young but does anyone know if this can all be caused by just anxiety?
