>>1 You don't have to try to be loud and 'obnoxious' if it is not in your nature to be like that. Quiet people are comforting as well, you know. The best advice I can give you is to just be yourself and be proud of yourself. Yes, you're quiet and shy, but that is not a bad thing at all. Think of it this way: you're a compassionate person who cares about how other people feel, and that is something to be proud of. As you start viewing yourself more positively, you will become more confident in yourself over time and you will find yourself opening up more. Also, try to spend time with your friend doing things you so absolutely love; sometimes in such situations, you will become so engrossed that you lower your guard and forget to be shy.
It's easier said than done, I know (heck, I am practically just like that), but it is always worth striving for. Hope this helps and good luck, Shuichi!
