Aysha,
I do feel for you. This depending on people thing is tricky. And I can relate to not wanting to taking a shower as I have to really push myself in that area. This month I called a woman for help and she said she'd call me back and never did. So of course this just makes me want to not reach out for fear of rejection.
I don't know what to tell you about the ride thing except to keep on trying and maybe something will turn up. Are there any meetings in your area within walking distance? Maybe if you were to get to one of these you could approach the chair and ask that an announcement be made that if anyone could help out with rides (and even if it would be one meeting a week that would be better than no meeting, right?) maybe someone could help.
Hang in there. We just have to sort of blow it off when we hit roadblocks and TRY not to take it personally. Easier said than done, I know. Eventually the right person or people will show up to help if we just plug along.
