You just need to become apathetic, nothing bothers you or shake you mentally. >fear of socializing and talking to people. I know your feelings, fear of being rejected, but I think at some point, you'll stand in somewhere where you have to say what you want to say no matter what it'll come out of it, somewhere you'll not care about what the other guy you're talking to think of you. I still feel the fear of socializing or give presentations, but I have courses at high where I have to give those presentations even though the hole class will see and hear me. Going to interviews and get those weird looks on their face. Although you still have this fear, but still you have to speak and let go and give it a try. Because at some point you'll succeed at one of those tries. Sorry for the grammatical mistakes :)
