I hate the dentist, I've had two unpleasant experiences with them and I try to avoid going to one because of those reasons. I'm terrified of them! As for doctors, I do get nervous at times but they don't really bother me. It's better to know what's wrong with you than leaving it go. If you're talking about operations and what not, I don't take that sort of thing well, I'd get really nervous. I had a procedure done.. last year now I think [not an operation] but I was really scared! It was all good though, turned out alright. It was even better to know I was fine!
