I would urge you to have a mental health evaluation with a pediatric psychiatrist. I see a bunch of red flags that could mean many different things. The increasing hyperactivity in the evenings sounds like daily mood cycling. Also, it sounds like he's not really sleeping. That may not be the case, but you should have him checked out for a mood disorder.
I'm sorry you are going through this. You've done so much already to try to help him.
