I know what you're talking about. As much as I don't want it to sometimes I feel E takes control of my life and stops me from doing things I want to do.
I recently turned down a nice job offer from a hospital because I just don't feel confident enough to do the job properly. The job offer was for a phlebotomist (drawing people's blood) and all I could think of "what if I have a seizure while I have a needle in somebody's arm"?? So I've been depressed due to the lack of confidence I'm feeling. I'm just going to stick with the job I have which I'm happy enough with.
Ok, enough of my venting! Just wanted to let you know that I know where you're coming from.
Take care.
