My psychological disorders...

Hey im Robbie, I'm 15, and i suffer from chronic depression, severe anxiety, and OCD. Basically the depression is because of my abusive family as a child, the way people seem to hate me immediately after meeting me, and the fact that I'm in love with my best friend and she doesn't love me back. I have a phobia of being abandoned because of past experiences and I'm left with 2 friends, one who is cool when I'm around him just the two of us, but joins the others in going against me if we're in a group; and the other one who I mentioned before that I'm in love with. The OCD is one thing that I have no clue what caused it, but I'm not a neat-freak, everything on my body has to be even though. For example if I bump into a wall on my right side I have to do it on the left side too otherwise I can't function. Another result of this is the way a thought pops into my head and I can't get it out, for example one of the things that bothers me are commercials that show people brushing their teeth (I have no clue why though) and it screws me up for the rest of the day. Basically what I'm asking here is whether or not there's anyone out there just like me? And I'm not looking to start chattin it up with people I just need reurance. But before you answer, lemme set some quick ground rules: no hate mail or anything making fun of me because I have OCD (I get enough of that **** from my "friends") and don't say anything about fake "teen-love" cuz that's complete bullshit. And thanks for reading all that by the way,
