I just looked at your profile. Your sister and your dogs are a great source of support as well. I identify with your troubles as I have a son with asperger's. I have another one with bipolar. And both of them have anxiety.

Just try to do the best you can with socializing. I think you will feel a lot better. Maybe you and your sister can join a club or do some hobbies. How about a gym or exercise program? You can meet people there.
