In the past month or so I've been getting them from time to time. Of course, it scared me to death when it first started so I got a ton of tests done, and it was nothing physical. I'm pretty sure it's anxiety. Although not just social. In class a few weeks ago we all had to go up to the board one by one and write something down, and I didn't know what to do. As I was sitting there in my chair waiting for my turn, I could practically hear my heart beating. Also I tend to get anxious at night now (don't know why), so sometimes if I get home later than planned or have to finish things before going to sleep, my heart is usually racing and pounding.
It's weird because I've been stressed a ton of times before and nothing like this ever happened. It's scary that it could cause such a strong physical symptom.
Just knowing that all my tests came back normal helps a lot. Now I know that when I get these episodes, ignoring them is an option. If I'm really stressed at the time it happens, it usually passes on it's own after a while. If I'm not stressed and it happens, I just try to breathe really slow and deep, and try to think about something that makes me laugh.
I hope this goes away for both of us. Even though I know it won't exactly hurt me, it's still scary.
