I know I keep focusing on the practical and that may not be what you are looking for. However, having been in such a similar situation, I remember how important it was that my T offered practical suggestions and help me create a plan for getting out of that situation and getting independent. I had a little bit of money saved up from babysitting and used it to make a small downpayment on a car and immediately started looking for a job. I found a job cleaning houses and actually made pretty decent money over the summers. When that place went out of business, I immediately found a job in retail. It didn't pay as well but it was enough for the apartment rent and my car payment and I got financial aid through my college and took out loans. Also, it turned out later that I qualified for public assistance.

I hope I'm not overwhelming you. I would just really like to see you create a plan. Just doing that will help you feel less helpless and trapped perhaps.
