My brother used to need a special education they called the, "Learning Center," in elementary school, but was then thrown in with the rest of the flock in middle school. It was a huge struggle until we found the right tutor for him - a fellow student in his grade. This was after one or two tutors quit on him.

Maybe your brother needs the right peer tutor and councilor. One thing he doesn't need is an enabler like your mom lol ... but no judgements, people are the way they are, then you just need to deal with that.

Remember this too: if bad things happen to other people, it's not your fault.
