I think it might be worthwhile to focus on yourself and your life right now, particularly your self-esteem, before searching for a potential partner.

You say not to bother asking why you don't drive. Fair enough, I don't either and there is nothing wrong with that. But I have a couple of questions:

1. What keeps you at home? It sounds like a toxic environment, and you are more than old enough to move out on your own.
2. Do you have public transportation available? I understand that it's not the most glamorous way to travel, but it is more affordable than cabs, especially if you are on disability and can get a discounted bus pass as a result.

On one of your previous threads, myself and several others offered input and advice...and I see you replied with "well then, I'm screwed". I am not sure what else can be offered at this point. I truly am sorry that you are struggling like this, but right now I think you need to focus on yourself before searching for a partner. Good luck.
