This sounds a lot like a panic attack
. I have them occasionally as well as acid reflux
. I know my acid reflux gets a lot worse in times when I am stressed. When I first started having this problem I thought I was having a heart attack
and dying. It turned out that nothing was physically wrong with me, but it felt so scary at the time. You should do a little research on panic attacks and anxiety
disorders and see if that sound like what you have. You can overcome it by talking to a therapist (it doesn't mean you're crazy) and learning how to do breathing exercises so you can calm yourself down. Hang in there.
