Susie,
I'm so sorry to hear he's struggling. At least gma and gpa are enforcing rules and consequences. It has to be hard on them, too.
I hope he's able to stop cutting. You know, the SI world is a very different world that I could not and did not understand. I have been talking to alot of teens that cut lately, and really, it's a realm you and I will never fully understand. I hope he gets help.
Sending hugs,
Janna
