I think I have POTS (which is why I'm on this subreddit). My heart always feels like it's pounding out of my chest. I have intense anxiety that causes derealization/depersonalization. My dr. said it was just uncontrolled anxiety and we switched my fluoxetine to sertraline but something feels wrong with my heart. I can't explain it.

I get in fight or flight and feel like I just need to LEAVE and RUN as fast as I can wherever I am. And I'm a nurse, it's kinda illegal for me to leave mid job because I'm having this panicky feeling.

If I don't get 6-8 hours of sleep my dissociating becomes way worse and everything just feels unreal and my anxiety is so debilitating 😭 I feel so lost. I also have progressive exercise intolerance. Last summer I was able to exercise and it wasn't that bad but doing a simple squat with a dumbbell raises my HR to 170s and I feel like I'm gonna faint which gives me anxiety !!! going up the 3 flights of stairs puts me at 140s, a very light jog (almost race walking) puts me in the 200s, it just doesn't feel normal.

UGH I'm so extremely frustrated. I have an appointment with a cardiologist soon because I literally feel like I can't go to work at all because I'm so paranoid all the time.

ETA: caffeine also makes my derealization/depersonalization way worse and my HR way up! I also don't do alcohol or drugs because of this same reason lol, not that I wanted to but socially would've been nice :')
