How can you raise your self esteem after an extreme life failure?

I've been through alot in the past few weeks. I lived in Maine, where I had to drop out of school because my parents were divorcing and couldn't pay for college anymore, and I couldn't get the loans to cover it. I could only find an awful job, and promptly got evicted and lost 40lbs trying to support myself. My ex dumped me so I'd have to move home, and now I live with my parents agian, which is just awful (thanks to the divorce). Being unable to support myself has just killed my self esteem and my faith in my own strength. I'm trying to make my own way agian, but in my mental state, I'm finding it impossible to make any headway. I have no money and no job, so therapy, medication or anything that costs money isn't an option for me. So I'm a broke, single, alcoholic college dropout with no prospects, awful credit and low self esteem, who lives with her parents and on their charity. Any suggestions about how I can reaffirm my faith in myself?
