I'm glad your son has you

A lot of parents are unwilling to admit their children have problems, and the little ones suffer for it indefinitely. Other children are unnecessarily medicated/overmedicated to make their parents' lives easier. It sounds like you had good reasons to take your son in to be evaluated. You found (obviously) excellent care, made the decision that was best for him, and he's thriving because of it. You're a good mother. Don't let anyone try to tell you otherwise

My father is bipolar. I don't blame him for passing it down to me, but he's never been medicated, so I have plenty of other things to blame him for.
