I'm the first to admit I'm not good at helping comfort people, but I'll try. To anyone that thinks you're alone: You're not. You might not see it, but there's a fairly high chance that someone you know, even a close friend, is or has gone through something incredibly similar to whatever is bugging you, or whatever is making you hurt. I know it's difficult to talk about it, and I know you might be scared; trust me, I really do know. You're not alone, and you might not see it, but somewhere, someone really does care about you, and wants to do everything they can to help you. The only reason they haven't is because they're just like you; they're afraid they'll mess up, afraid they'll make things worse, and they're waiting, hoping they won't have to make the first move. And if you make the first move? You'll be proud of yourself, and things will get done faster, and then it'll all be over and you can do anything. After that, you're free. The only thing holding you back right now is you. You need to figure out a way around whatever you think is a problem. It doesn't matter what it is. Think about it, war game the solution if you want to. Just do something. Even if it's something as seemingly small as asking out the person you have a crush on, it's progress. So go do something, anything that you want to do, just so long as you're sure it's something you want to do. Don't do for other people; do for you, because if you don't, there's no guarantee anyone else will.
TL;DR: Go read it, I'm trying to get you to do stuff, not skip to the easy part.
