Hey, I fear growing old alone too.
I hope you find a place where you can feel safe and hopeful about the future. I think I'd find a half way house depressing.
What kind of progress have you made over the past two years? Can you list it no matter how small it is. If you have made progress, then you are succeeding in your battle. If not, then you are still alive. There is always hope where there is life. I hope you find a way to make it through this.
