When I started medical school, I was pretty sure I wanted to do EM. Once I figured out that EM is mostly primary care, but for a population that won't take responsibility for folllow up, I eliminated that.
I wanted to look into anesthesia, but the way my medical school was structured we didn't have much time for electives. We were assigned random numbers in a lottery system and signed up for rotations based the numbers. So I never got a chance to investigate anesthesia. Nothing I could have done about it, but i regret that to this day.
I wound up matching in gen surg, but didn't finish. I'm still in limbo and will probably wind up in anesthesia. Many factors drove me out of surgery, one of which was laparoscopy, which I hate and never got very good at. Also rounding. I don't ever want to round again! A large part of me is fed up with medicine all together. If I could come up with a workable non clinical option, I'd take it.
