Have I made the wrong career choice?

I just graduated with a teaching degree(elem) about a year ago. I'm wondering if I made a poor choice. My problem is, I'm really not a people person and I don't think I have the personality for this, but I do like kids. I find that people are judgemental, and parents can never be pleased. I feel tremendous pressure to please parents, admin, and state big wigs who visit clrooms so much that I'm scared to death I'll mess up that I get stomach cramps. I try to be perfect in order to avoid problems, but it's so stressful that I can never relax. I like to see kids learn, but, it comes at a huge emotional and physical cost to me. I'm pretty shy, and thin-skinned. I feel that in this politically correct world, I'd better not slip up and say the wrong thing because others get offended so easily. Like being under a microscope and people trying to find fault with you. It just turns me off due to monumental expectations, and my shy, quiet, type B personality. What do you think?
