I'm sorry that you're having such a tough time, Penny T.
I can relate as well. No friends for me either. I'm not tough to please, it just takes a very long time for me to let my barriers down. So, I seem pretty harsh and snooty to those who don't know me. I'm the opposite on the inside!
Have you thought about going to a local support group with others who have the same (or similar) physical illness? I did go to a TBI group for about 6 months or so, a few years ago, and that helped me feel less alone. Perhaps you can find a support group in your area?
If not, you're certainly welcome to PM me. I'd be happy to respond ~ offer feedback or just a shoulder, if you like. Take care!
