Never, ever give up. Look into the possibilities of what is possible without having to rely on another person to do something. JD had some good ideas, but while you try to get the letter on your disability, call around to some of the other churches you might be interested in and talk to the pastors about your lack of transportation and need to be reconnected to a community. Sometimes churches have volunteers who will give rides and support. I will join TheByzantine in praying you see hope and possibilities.
