I’d find a different therapist - I don’t know you (I do love your namesake, though - I’m guessing you’re a fan of Terry Pratchett?) but I don’t believe you’re beyond help. Every therapist has a different approach, so you might still be able to find someone you could make progress with. Ditch this therapist, though!
Also, attraction isn’t solely about looks, even though being handsome admittedly makes things easier. I like being single, but if I had to pick, I’d rather be with a less physically attractive man with a nice, kind personality than a handsome one who didn’t really care about me.
