Skater, I know everyone has said it but they are absolutely right. A psychologist is a whole different kettle of fish. They WILL listen to you because that is what they work with. Talking and listening is thier job. And I can tell you from experience it really can work. It's down to you. The drugs, and I'm talking about the illegal ones here, won't help cure anything. I was addicted to dope as a way of avoiding my depression too and it wasn't untill I chucked it in the middle of my therapy that I really moved forward. Take it slow, but there is a way out. When you look for a therapist it is important that you find someone you feel comfortable with. Someone you are happy to talk to.
Good luck. You can do this and come out stronger at the end.
