Go see a shrink as him about Paxil, Zoloft, and Wellbutrin.

the best cure for shyness is success. go win at something.
muscle relaxant works too (alcohol).

if you don't like talking to people, realize that most successful conversationalists don't say jack, they just listen, nod, and smile - do that and people will think you are a great person to talk with, even though they are doing all the talking.
doesn't matter what they are saying, just nod and smile, they just want to say something.
if you don't like public speaking to groups, just realize that 90% of the people in the world are idiots and won't understand or even listen to what you are saying, the rest know what they are talking about, but aren't likely to call you wrong - so talk away.

I used to be shy, thought people were watching me and mentally critquing me since I do that to other people. then it hit me one day that most people are too self absorbed to even notice anyone else, so do what you want and nobody will likely even notice.
take new york city for example, you could walk down the street in a jock strap and an umbrella singing a song and hardly anyone will even look at you... and those that do are tourists.

and now I'm rambling.

just reember 2 things 1)most people are idiots and 2) act like you know what you are doing - rememeber that and you'll get a lot farther in life.

so I just imagine someone that is psyched to be in a room full of people while they are sweating, shaking and shitting their pants.

Here's a persoanl experience. when I was younger I had this problem.

My aversion to social contact meant I was alone a lot. while I was alone I started playing basketball....doing things on the court.....it sounds weird but that became not only a sport I liked to play, but a world in which I lived...I wanted nothing to do with the outside world....for me, playing basketball was my "time away" from reality.

I was liked, but only for the things I could do on the court. No one really knew me...I kept it to myself.

When I was on the court, I wasn't shy...I was expressive, outspoken, a leader. But off the court I mostly kept to myself. I wasn't paranoid or depressed, but I would go to the park and play by myself rather than go out.

As the time went by, I got really good at basketball. And I became even more the charismatic presence in that environment. This went on for years. Eventually, I got a scholarship to a d-1 school in a major conference, played four years and graduated.

When I went away to school, I was again popular as a basketball player. But in time, this translated into making good friends, and socializing became easy again, and I am no longer afraid of it. In the military I was often sent to new places knowing no one....this would have intimidated me back in the day, but it was not a problem anymore.

So I was able to use the negativity and turn it into something positive, and through that, leave shyness behind.

Perhaps you can do something similar.
