I agree with Eric Thom, he has gotten away with too much for too long and it will only continue to get worse. Eric says it way better than I do. And yes he does need and evaluation and diagnosis, but good luck with that.

Needs to get a psychologist evaluation for a diagnosis

I also agree with the epilepsy team. Also if they ever act like they are going to harm themselves or say something about it or harm others even in passing call the emts and they will take them to the hospital and evaluate and transfer them to a place that can help them. Here in our state they have numerous places that take people with and without insurance just in our area from people who had to use them on mentally ill family members. They are all fine and working after getting help. One still sees a therapist but has a good life now.
So watch for anything depression can get really bad and needs intervention with emts sometimes. Best of luck with dealing with this tender situation. 🙏

I agree with the epilepsy team post and hang in there and try and stay pos,
