I was one of the few folks in rehab who didn't get visitors.
My parents sent me nothing, and did not call.
That was a hard slap in the face for me, and today I'm grateful for that.
That was the beginning of me seeing the damage I had inflicted on loved ones, and now with having an addicted daughter of my own, I understand the pain from the other side.
You're doing great in reassessing what you will/will not do for him at this time.
