Jelly, I agree and understand diagnosis isn't always useful. It provides some insight though.

Being with people might be helpful but since you have difficulty being with people, it might be useful to find out why?

You keep asking what's wrong with you but it's very difficult to tell, we can only make guesses. Only people in real life can tell. I agree that diagnosis will not cure people.,But it could answer the question: what's wrong with you. Then you can start looking for strategies.

I am sorry you had crappy childhood. But at your age you will not find people to take care of you. It just isn't possible. But if you are having hard time functioning there is some help out there. Professional help. It's terrible that your therapist isn't saying anything about you staying in bed for two months. She or he needs to take it seriously!
