Figuring Out What's Wrong With Myself?

So I'm 35 and have no family or friends. Everyone eventually hates me.

My therapist seems to think there is nothing fundamentally wrong with me and I've just been around the wrong people. But I don't agree. Surely SOMEONE would be OK with me.

I guess I just want to know how to figure out what are the things about me that everyone hates so I can change them. I'm happy to change everything about myself - I just need to know what!
