Yet you spent most of your appointment talking about it. I know therapists listen to their patients, but I see that you can do the same with other people who don't know about music. You said that you don't talk because you don't relate to others, try the opposite, talk about your interests and see others who don't relate how they react. For me if I talked about a topic with people who aren't familiar with it, I would present it in a different way than if they were familiar with it. If they asked more, I would elaborate more.
