Why do I faint and have a low pain tolerance?

If I get hurt really sharply or suddenly, I end up passing out. This has happened once when I slammed my finger in a doorway, once when I bashed my elbow on the shower wall, once when my finger was held in an awkward, painful position, and once when I got a flu shot. Why do I pass out like this, and why do I have such low pain tolerance?

I need some good advice. All my life, I've been raised as a Catholic. Both my parents are fairly religious, but I have completely lost interest in Catholicism as a religion because I feel it does nothing for me but preach and tell me how to live my life. It has now gotten to the point that I have become very interested in alternative religions, so much so that I want to change faiths. However, I'm terrified my parents will find out. What should I do?


Is it important to have a primary health care provider?

I've been hearing a lot about having one health care provider follow my medical history, but I'm fairly healthy and don't have a chronic disease. I've been switching from my local doctors when I'm home to the on-campus docs. Is it really that important, given that I'm a healthy individual?
