I had one about a year ago. It was horibble I actually thought I was going to die. My hands were sweating, heart racing, legs felt numb. Since then I haven't had one, but I do have small ones. When I get sick for anything I start to get anxiety and it just makes everything worse. It's hard to explain. For example, when I started having signs of a bladder infection last week, such as burning I immediately started panicking, freaking out and crying. It was before I knew what it as because I never had one before, and then when I found a bladder infection was ok and treatable I calmed down a bit. I was never like this before that one big panich attack a year ago....Anyone else goes through this?
