I went for my second 'pushing myself' session today with my heart event monitor. Stumbled a bit and my vision went a bit blurred but nothing too out of the ordinary (for me atm). But have been feeling pretty off all evening since. Keep getting icky pains and twice before when I've gotten icky pains they were followed by very scary sudden palps. At least I'm wearing a monitor this time but I'm so terrified of it happening again. Felt like my heart was trying to break out of my chest

Why is this happening to me? I'm only 21. I just...gah I can't describe my terror of those palps. I've had fast heart a lot, but these felt way more extreme. I think I actually have ptsd about them.
