I feel so alone

I've suffered with depression for about seven years now and I am getting quite sick of it. I've been bullied, harassed, betrayed, etc. Its gotten to the point where I hide from society in general. Just recently, I lost a great friend. She hurt me real bad and doesn't know it. I've developed many psychological issues from this never-ending depression such as, anxiety, OCD, paranoia, and I'm also anit social. I also tend to get really angry at the littlest things, I lash out at my loved ones when I don't mean to. I never like to talk about my problems to others because of my inferiority complex and I feel like the world had turned on me. Like I'm a target of constant bullying. I'm struggling financially to stay in college with a dead end job, it makes me feel like a loser. I can't get professional help due to my finances so if anyone is reading this, please don't recommend that I go to therapy. I just really want someone to talk to..

Hi, Ezio! I've been bullied and harassed and hurt too and I know what it can do to a person. You can talk here about anything you want.
There is nothing shameful about working to pay for college, you're doing a very good job and taking care of yourself.
What did your friend do?
