My spouse was just diagnosed (FINALLY!!!!) with ADHD. I had suspected it when our first child was diagnosed a few years ago, but when he brought up the topic with me, then his doc, our answers were both a resounding YES!
We have done the testing, the meds and the treatment has started. It isn't a magic bullet but drugs are really helping. I told him it was a matter of UNlearning brain patterns he has had for decades. It won't go away overnight.
He looked at me thoughtfully and said, "yeah. kinda like grief."
Well... when you put it THAT way...
