All that you need, my friend, is SELF- CONFIDENCE!
it's obviously easier for me to say it than for you to do, however it really is just a situation of mind over matter. I used to be too shy to even call for a doctor's appointment. Then one day i decided to get out of my shell. Haven't looked back since. Keep trying, and you can't possibly fail, man!
You might come across assholes who will try to put you down, or will dislike you for whatever reason, but if you're a good guy, and always keep looking forward, you can leave those dickheads in your dust.
The most important thing about self- confidence is that you make it yourself, so you can have as much of it as you want!
RAWK!!! >_< \m/
