I'm low on confidence and am shy, I mean, I'm no way a looser, but I'm one of guys that is payed to make others feel better, but it's mostly jokes and I ignore it, however, I'm shit at sports and stuff like that, so I am left out sometimes.
That, and being payed out and excluded, and backstabbed, and laughed at, and rejected, diminishes my confidence, but I just pick my self up, find out what I did wrong, and continue on my day.
Anyways, I have freinds to be with, and people who'd like me to be with them anyway, and I can usually find something to do (I'm that busy), and can make sure I'm included (By being freinds with the right people or brining the ball for a game or something).
However, my confidence is realy low in asking chicks out, I still want to ask one out, but it's kind of late now, since she has a bf, and a massive slut.
So basic tips for those feeling bad, talk to to a freind, express your self through song or a poem or book or boxing or something, keep trying, and don't be afraid to be rejected, becuase the more you try, the more likely you'll be accepted, make it clear to the person paying you out that you don't like it, becuase 9/10 they're joking, trust me, I joke with people all of the time, and they get offended, if you hate them, ignore them, stay away from them, if they hate you, do the same, and eventually they'll get over it, unless it's genially your fault, then speak to them when you can, and if not, they're not worth having a place in your life.

Remeber, in every topic, you can find at least one, or maybe even three things you're really good at, well, apparrently anyway.
