I had a very bad panic attack about an hour ago. See i have mitral valve prolapse and panic attacks occur in about 90% of people that have this. My heart races all the time and i get out of breath alot. Well i couldn’t get my breathing to slow down and to calm myself down i decided to go for a ride well i got stuck in traffic and started to hyperventilate and i almost parked my car in the middle of an extremely busy highway to find help. I drove far enough to get to where my friend works and when i started talking to her i calmed down a little. But being that my hearts still racing and i’m still out of breath i’m scared that its going to happen again. Any suggestions?
