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?


Why is my wife losing hair?

My wife has noted that she is recently losing hair at a much greater rate than normal. She feels her hair is significantly thinner (less density of strands) than in the past. What could be the cause of this?


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?


Why can't I communicate with people anymore and what can I do about it?

I've been "plagued" with this problem for at least a year now, and it seems to be getting progressively worse. I feel like I have lost the ability to communicate with people. Sure, I can make small talk about the weather and stuff like that, but I feel like I've lost my openness and humor with people. I figure I am changing and learning new things about myself, but this is getting ridiculous because it is affecting my social life drastically.

Whenever I get into a conversation with someone, either on the phone or in person, I become flustered. I have a problem with eye contact and I become very hot and sometimes I turn red in the face. Worst of all, my mind seems to be blank all the time and I can't get past small talk (even with my friends). I put a lot of pressure on myself when it comes to maintaining eye contact and continuing a conversation, but this pressure seems to fluster me more. I also seem to notice long pauses in conversation which I interpret as moments of awkwardness.

I realize that I have nothing to prove to anyone, but this problem still persists. I used to be very social before and now I am not. So what must I do to get by this? I figure, I'll just deal with it and it will go away, but it's been going on for too long. What must I do?


How can I stop being shy?

I'm a graduate student who is still trying to cope with shyness. I have extreme difficulty talking to people — even to people I see and work with everyday. I know making friends takes time and patience, but I seem to be at a loss as to how to develop acquaintances too. I've always been antisocial, but I never wanted to be. Who does, right? But I just don't know how not to be.

I'm studying a profession that requires a lot of personal communication; so, it's making me nervous and depressed whenever I can't overcome my introvertedness. But it's not my career that worries me the most. I sense my emotional well-being deteriorating every time I feel myself lost around others. Is there anything I can do to overcome shyness? I've been reading articles about the antidepressant drug Prozac and its success on passive people — should I consider it? Or are there places I can go for therapy? Thanks.
