I go to therapy, and I don't feel any shame or guilt, but I wonder if all the therapists in the world put together know what to do with me.

I'm a 30 year old guy with no social relationships. I have no friends, acquaintances, or regular contacts that are girls. I've been in therapy for 3 years, and my therapist says it's not possible for a grown man to have no social contact with women. She wants names, examples, stories from my childhood, high school, college. I have nothing to give her. I'm just a person with no relationships at all. I don't have regular contacts at my job, I could drop dead tomorrow and nobody would notice. I eat alone, go to the cinema alone, go to concerts alone. I don't feel any shame or guilt about it, and I don't feel like it's my fault. I do everything to change my situation, I work out to improve my looks, I read books on social skills, I go to language schools to meet people. But I keep failing. I've been in therapy for 3 years, and I'm starting to wonder if the whole psychiatric community has a slightest idea what to do with me.
