I'm so sorry you are having such a bad time. My heart hurts for you. I don't have much advice but maybe a few ideas. Have you looked into nursing? When I started out I got my LVN in one year. It pays a living wage and sets you up for further advancement by getting a two year RN from a community college. You can make a very good living that way. Another idea is is as a beautician. It doesn't take a long time to get qualified and I have been assured by people in the business that it is recession proof!
There is also a long list of help numbers in the top of this forum called Depression Resources.
I really hope you find what you need,
