I can't stop. I'm so depressed.

Been gambling for 4 years I am 22 now. About $40,000 in debt not including the debt I defaulted on. Life is miserable. I been able to stop for periods of 3 months but I keep relapsing. It's funny because I'm not addicted to anything else. I'm stuck working 60 hours a week at a job that I hate, a car loan with a blown engine with severe negative equity. There is nothing I can do. Been living alone for the past 4 years I can't even talk to anyone I am so embarrassed. The worst part isn't even the money it's the people I've had to push away and the time wasted in order to support this addiction. Nothing helps.
