I don\'t know!

I am so freaked out about the future! I'm really worried that I will turn out like this guy, my sister saw. She said he was sitting in this meeting and someone came up to him and asked how he was, and he didn't answer them!I swear if I don't overcome my problem soon, I am going to go so down. And I am so afraid of that! Because if I go down it is so hard for me to get back up. And I feel I shall never achieve my goal. I don't even know why I bothered to join this site, I mean how is it supposed to help me? I would be helping myself more by just going out in the world and speaking to people! But I just can't do it! And I don't know if I ever shall.
