No I don't think academic success measures ones intelligence. I know the details of your childhood from others things you've written. You were so intimidated/abused by your father, when you didn't do well or didn't understand something - this started a pattern of associating stress with learning. Unfortunately your family didn't know you were Autistic with Aspergers. Thank God you finally got the right help and then you blossomed. You were actually a diamond in the rough and just needed to find your niche.

I think your past interfered with your ability to learn in university and the university should offer help to students who need accommodation - there are some good universities that nurture students like this. Its also known, some with Autism have extraordinary talents and you have this. Yes you are very smart and you also write well. I know you also struggle with the need to be perfect and that's from your father. Try to resist this, since you don't want to impose what your father did - you're free now, although I know its not easy to relearn when we weren't shown better. You were a child who needed help, but that doesn't mean you weren't smart. Accent your positives and you're lucky to have these talents. You're a survivor and I want you to believe in yourself.
