Once again, faggot. We are dropping the gamespeak to discuss your obvious problem openly and clearly.
The world is large, there are a lot of people in it. If you go talk to the gas station attendant and make a flub? it doesn't ruin your life. She'll forget it in 10 minutes, and a normal person would too. You sit there agonizing about it, thinking she's telling everyone you have a small penis.
Basketball players practice in games that don't matter. Charismatic people practice with people that don't matter. Go to a mall. Go tell a girl she's got a cute sweater.
Wether you succeeded or failed (like you're telling yourself you will right now, because even the very idea of success is too insane for you to consider as you gorge yourself on the fat teat of defeatism), IT DOESN'T FUCKING AFFECT YOUR LIFE. If you fuck up royal, like slip and yank her shirt off while throwing a coke into someone's face? She'll forget it in a few *days*. YOU will probably go kill yourself at that point. So either way, net win for the world, you either get better at socializing and stop acting like a faggot, or you kill yourself and stop this pathetic snivelling.
