I'm 14 and i need some advise?

I'm 14 and am almost exactly the same. Recently I joined speech and debate and that really helped. I drink also and it is mostly because I am more social when I'm drunk. Just try to talk to someone. Tomorrow just say hi to one random person. And then next week do that twice. And then three times. U will eventually gain a liking of life/people. Don't worry. It will get better :)
