Phoenix,
I also don't have a car. I don't drive at 32 years old and never have. I am lacking most of my peripheral vision, I'll likely never drive as I'd be a danger. It does suck sometimes tho, towing three kids around by foot.
I try to think of the positive things about walking, like getting exercise, feeling the breeze, getting to look at things more closely, getting to stop and look at a flower or bug if I want too, also the big plus of doing something good for the environment.
I sort of just force myself out of the house, I'm on disability and do not really have any friends here, I will sort of make up things I need to go out and do and just force myself to do them. If I'm really no doing good, I will only go places near my house, if it goes badly I can quickly return home.
Did you make it to your meeting? I don't think your supposed to magically be "ok" now, and quitting a long outpatient therapy can leave you feeling a little insecure or vulnerable at first.
