4 months ago I used to get afraid of things, and worry about things and then I learned that all that was just a manefestation of fear. I learned to control it and now I don't worry about anything anymore. I still have problems but they dont really affect my mood. A couple days ago, I had just finished smoking and I was sitting at the computer and my heart beat felt fast, which was normal but it was bothering me. Soon I had a feeling in my chest, like there was pressure in there and something was blocking the pressure from being let out. Now I think it was just some gas in my stomach but at the time I thought I was going to have a heart attack. And I lost control and couldnt convince myself that I was trippin. What went wrong?
