I am suffering and nobody knows

I have been severely depressed for the last 7 years of my life. I’ve suffered from extreme social phobia, moderate ocd, and recently found out I have aspergers syndrome. I have no friends, no social life, and it’s only getting worse. Nobody in my family knows of this, and I’ve kept it a secret from everyone. I just suffer in silence, waiting until I can finally die. I’m barely able to keep a job and I’m going to be forced to drop out of college because I can’t handle being around people. I’m 23 and I’ve never been in a real relationship. I just sit in isolation, day after day, wondering why I’m still alive.
