I completely understand. Both kt & wm want friends in the worst way & in turn end up with some of the worst friends.
Neither of them need a difficult child as a best friend. A couple of the hardest concepts for my difficult children to understand is not caving to negative choices & that you can't buy friendship.
kt & wm are taken advantage of a great deal by their "best friends".
On top of that, the very learning/treatment environment they are in surrounds them by other difficult children with some of the same or worse issues.
I'm sorry that your difficult child is so very easily swayed & so sad this morning.
