I seem to have a lot of the same questions about my son, but I unfortunately have no answers.
My son is 14 & has given up on school. He says things like "Why do I have to go to school - aren't you supposed to learn things there?"
He is gifted in some areas, but seems almost disabled in others. He is completely lost and conflicted.
Sorry I am of no help except to let you know that there are others who are in the same boat.
I'm very sorry for what your son (and you, also) is going through.
While I certainly don't know the details of your situation, I was miles ahead in writing and languages, but had trouble with the most simple math. --I'm a 35 year old Mensa member with a 5th grade math level. Of course, I've never had help with my problem.
I hope you're able to find the help your son needs, whatever it may be.
I wish you the best.
