Bunny--
I read the whole thing. Sounds so traumatic and awful. Since you can't drive, if you eventually move out, you will need to live in a city that has decent public transportaon. There are many young people today who can't afford a car. When I worked in a call center, many of my coworkers commuted via the bus--occassionally, they needed some good rain gear. Keep researching your options, maybe research about if their is a city in Texas that has subsidized housing that you qualify for or perhaps look for a roomate. I know your anxiety and all the rest makes it scary to take chances but you need to try. Seeking therapy is a good idea--there are some therapists who might be able to help you take the chances you need to take in order to get on with your life. If you have been on disability for 2 years, you may have Medicare (I think it pays 80% of the cost for therapy) and you also might qualify for Medicaid, food stamps and a free phone (https://howtogeton.wordpress.com/). You might qualify to get aide to return to school also (https://fafsa.ed.gov/). My hope for you it is that you find more help. You would not be taking advantage of the system. If you qualify then use the system to help you heal. You probably have so much potential once you recover from this trauma.
It must be so hard to live amongst people who hurt you so much and will not admit how much they hurt you. I am sorry this happened to you. <<hugs>>
