Unhappiness.

I went out tonight to see my aunty, and to get a tarot card reading.
I feel upset because I can't be as social as I want to be, the steps to making myself more socialy adept would be to increase my confidence in who I am (who is that, anyways?) with that, I'm sure I could be a lot more of a contributer into social situations, but how?
I have been meditating on the mantra "om mani padme hum" the prayer of compassion, and the healing of the heart for about 2 weeks now, along with some other meditation techniques, and it has proven to increase my inner peace and happiness and joy, but thats not enough. I can and now am more of a half full person rather than a sulky bitch, but I need to get it more out in the open, express myself and enjoy it at the same time.
The root of this is definatly confidence in being myself with other people, I fear that I won't be able to contribute properly and make a social situation worse, people sitting around, not talking. (I know and have experienced the reasons for this)
I can see it in me, the confident, emotional, responsibile and awesome Jim, and I know that when I get me out of this struglling stupidity, that I will be much more complete, and much more able to achieve even greater goals than I know now.
I am unsure how to bring it out, meditation alone will not sufice.

Having a new job is really inspiring, i'm surrounded by very nice and awesome people.
I want myself, I crave myself.
Please show me how, please help me understand this struggle so I can exceed my own expectations and live the life I have drempt of.
And if you can't, tell me why..?
