Okay here's my take:

You made some bad decisions as a kid, which we all do. You have depression, and many of us do, including me. But you can work through this. You can develop coping skills. If you have insurance ask for a Therapist to do CBT with you (Cognitive Behavioral Therapy). I think your plans are great. Go back to school, get your education, get a job, and have the life you want. You CAN have the life you want, you just have to dig in and work for it. And it will be tough with depression tagging along. There will be struggles and you will need to go easier on yourself and pace yourself maybe slower than colleagues, but it can be done.

I think if you go through with your plans you would be an inspiration and role model to many.
