Marvel, you are not alone!! My panic attacks make me faint. I have had them for two years, and had to quit my job for fear that I would do this again at work (where my second to the last one took place). I tried to work at another job, but had another mild attack and decided that this was not going to work. I am now, not working. Although I feel better, (some of my worries have been taken away), I still do not feel as though I can take the pressure of my main fear of loosing my job.
Still working on things, going to a pdoc for help to resolve some pretty deep (childhood issues) fears that I have. Maybe with her help, one by one, they will dissipate and I can live a normal life.
