It's in your Control Panel (strip of gray buttons at the top): do you want ppl to contact you via PM, email, etc.
I read some of your posts and see you're in the U.S. — sounds like applying for disability is a real possibility, especially with heart stuff going on. Maybe temporary disability can help you more immediately, too. I think there's other types of that kind of aide available (food stamps and so forth). Have you tried any of that?
And I don't know a lot about the program, but "free phones" are sort of part and parcel with government aid. They give you a phone and minutes and you could PROBABLY port your current phone number over to that.
22 days for your car... yeah, prayer. But I'd let the phone go (or get a free phone) before letting the car go, unless you're in an urban area where it costs a lot just to park your car.
