I totally understand that, that's what I started doing every time I started feeling my heart beating a little bit faster than normal. All I succeeded in doing was scaring myself, and making my heart beat faster. I don't find it stupid at all, I agree with you 100%. It IS extremely hard to exit the loop once you're in it. I was prescribed 2 different medications: Effexor, and Ativan. I don't know if you know anything about them, but Effexor is a medication that you have to take for about 3 weeks to let it build up in your system before it starts to work. Ativan is a pill that you can take every 8 hours if you need to, but it's extremely addictive. Basically, it's a mild sedative, that allows you to chill out and not worry so much. I don't recommend either of them to anyone. I took Effexor for under 2 weeks, and found that if I was even 5 minutes late taking my daily dosage, I started to have chest pains that would shoot into my left arm. I stopped taking it a couple days later. What helped me was talking to people about it; mainly my boyfriend and my Grandmother. They've always had the ability to make me feel better, and talking to them about how I felt, helped to relieve some of the stress I was feeling. Also, I find that laughing at myself works wonders, as silly as it seems, it's almost like NOT laughing, is giving the "panic" some power over you because you accept it or something.
