I really relate to what you wrote, Gas. I also have a somewhat dim view of a lot of humans. The good news is, there are a lot of really outstanding people here on PC. People who do care. People worth communicating with. I have basically three friends, only one of whom do I ever hear from. Three "family" members, one being my 11 year-old daughter, who wants to help, but she's 11. So, I don't have much support. But I have a ton here on PC.
So, you're not alone. Hang in there. Do you have a therapist? Maybe you should see him/her or get one. Wishing you all the best--
