ADHD can also have tie-in with minor symptoms of ASD, which could negate the overly-emotional part. Or at least the outward expression of it.

So smart, but struggles to keep up with homework

I just stopped doing homework altogether. It stressed me out, so I avoided it completely. Besides, I learned a subject by reading about it in our textbook, or studying it in class. I felt like homework was just busy work, hammering in concepts I had already learned in school.

I aced all my tests, but lost tons of points for never turning in homework, so I graduated high school with about a C average. It didn’t matter; I got a great IT job in the military, got an excellent pension and full medical/dental benefits for life, and fully retired as of 38 years old. Who needs homework?

I mean some of those are literally just normal kid things.
