I can hardly describe what it was like when I was going through this. My head suddenly was in a cloud, my heart raced, I had to get away!!! I thought I was going to pass out, I thought I was going to have a heart attack...
I didn't. The last time I had one was when I was at Target with my wife. I told her we were going to walk around the store until I got rid of it. We walked around the back wall of the store 3x... I don't think I really felt any better when we left but I had the satisfaction of fighting it and having the confidence I wasn't going to pass out or have a heart attack.
It's not so easy, fighting those feelings but sometimes you just have to do it in order to move forward in your life.
