You need some stability. It sounds like moving around and shifting course frequently didn't work out too well for you. So make up your mind to stay put where you are for the next 6 months, or move again, and then stay put for 6 months. Sign up at the local state employment office. Go there every day that you are off and follow their suggestions. Put in time there just like going there was your job. When you get a job, stick with it for at least 6 months no matter what. I think you're rushing too fast from one thing to another.

One year, when I was young, I had 6 different jobs in one year. Then I said to myself: "I'm going to stick 6 months with the next job, if it kills me." I hated it. (It was a pretty lowly job.) Then, by the time the 6 months was up, I was doing good in it. I stopped hating it and it became the foundation for a career. I got more training in the field and I came to be able to support myself.

If you have a diagnosis of Depression from a doctor, you can go to a state agency that will help you. I think most states have something with a title like "Division of Vocational Rehab." Look that up for your state, then hook up with them. You're still young enough to get out of the pattern you're in. Forge ahead. You need to have a place to report to on an almost daily basis. That gets you in the habit of showing up faithfully somewhere. That breaks the spell of paralysis that you feel staying at home thinking how bad things are.

You might be surprised at how much better you can feel taking these steps. I know it's hard to start.
