Listen to Nathan and Zyg. They both are giving you the two main factors invlolved in "psychological disorders". The problem lies somewhere in the hazy gradient between your state of mind and a chemical imbalance. You can't change your state of mind mentally if your state of my is a result from your physical body.
I used to be like you, always finding myself getting exponentailly nervous as the number of people increased. I have learned to grow out of that, for the most part. I still get random rushes of nervousness sometimes, but I can easily control it now. I take vitamins daily: A,B-50,C,D,E, Bivoflavenoids, pantothenic acide, folic acid,calcium, and cholean and inositol. But I think the one of the main fators in helping me was Ginko Biloba. It's amazing how much ginko biloba helped me out. I just take the daily recommended dose, and within a few hours, my mind suddenly becomes clear. My attitude is always positive and I never got nervous while taking ginko. After a while though, my body built a tolerance, so when I took Ginko, I got the opposite effects for some reason. So I just stopped taking it, and now I find myself much better off than before I took it. It's like Ginko Biloba showed me how I COULD be and after I stopped, my mind just adjusted to it. I've tried all the herbs out there and Ginko was the only one that did anything for me. You might want to try it sometime. I found the best manufacturer of Ginko is "Sundown Vitamins". For some reason, they're ginko had the best results.
Sometimes herbs are better than manufactured medicine, and I think this is a great example. As the bible says, God made the plants and the trees "and he saw that it was good".
Herbal remedy is only part of the solution though. You need a good, nurturing environment. A caring girlfriend is nice to have, good friends that don't trash you all the time, doing things that please your soul. All of these things will help out greatly, and can do much more than any herb or drug can. Just my $1.02,
