Okay so I'll pretty much throw in my spiritual 2 cents here.
So from what you're saying, it's as if you're depressed or feeling animosity toward others because you are alone, or you simply just hate everyone. I used to be in the same position as you in a sense. But I learned that things aren't always gonna go your way. You'll run into crap. Maybe a lot more than others but that just makes you who you are as a person. And as a Christian, I can say that you aren't alone at all. Despite not having physical friends, God is everywhere at all times. Although, I really don't know if you are a Christian or not. But to me it sounds like you aren't at all.
So in that case, it's almost as if you have no where else to turn. Seeing as other people won't help you, I seriously think that God is the only one who can actually have an impact in a scenario such as this. And it's not so much that it's hard to establish a relationship with Him, because it sometimes is, it's just that you're approaching the wrong people about it. Instead of talking to therapists, talk to pastors if you can get a hold of any. If not, talk to other Christians around you and hear their two cents on the matter. Because whether or not it's hard to open up and tell someone something like this, there's always someone willing to listen and build a process in which you can escape from the depression you're in.
