Yes, one doctor actually diagnosed me as depressed. However, I think my episodes of depression are transitory. Generally I have some reason when I feel depressed. When I don't think I have a reason for any given emotion I try to push it aside.
This doctor thought the whole reason I wasn't dating was because I was depressed. However, I think that's because of AS. My desire to form relationships with people really doesn't vary much with my emotions. If anything, I desire human companionship slightly more when I'm depressed.
