Just so you know, you're not alone.
I know that doesn't help much, but it's true.
I'm the same way. Major major social anxiety. Major major depression. The sad thing is, even when I do get close to someone, it's just a matter of time before they see what a freak I am and leave.
But,
i've adapted the thought that i'm even tougher than the rest of the world, because I (fear?) them and overcome it on a day-to-day basis. Alcohol and drugs help me majorly, but I know it isn't right.
Dr. Prescribed drugs may help you a little (they did for me sometimes) but the sad thing is, we're doomed. I've yet to find a 'cure' for this disease, but so far the best drug is talking to someone like-minded and being morose together.
Let's go get a drink, eh? At night, sunglasses, you and me. Let's go.
