I'm glad you have been able to find a doctor that is helping you, that is not always easy.
As far as your family is concerned, it sounds like you are doing your best to get along. I think you have probably already figured out you cannot change your family members. All you can do is try not to let them get you down.
As far as other families, there are plenty who live with disfunction. Even as your read more on PC you'll see a lot of people have disfunctional families and get by the best they can. Sounds like you have a good head on your shoulders and have learned a lot about people. Just keep working on yourself and try to get along with the other best as you can.
