I know how you feel. I wish I had good advice to give, but I can only relate, for what that's worth.
Sometimes I feel so alone that it's almost suffocating, like I get terrified at how lost in the world I am. I guess that's not necessarily true considering I have my family, but things with my family aren't that great and I'm not with the supportive ones right now.
And sometimes the pain of loneliness is truly unbearable :

: That's not to sound emo or anything, it's just a very very difficult feeling to cope with. So painful when all you want is at least ONE human being you can connect with on a deeper level and spend time together.
