I am so sorry you’re going through this. You’ve gotten a lot of good and very valuable advice here, you should give it all consideration. Although, with that said, we did pretty much the same thing to my son. He has all the same issues (and more) that you are going through. He now tells me, five years later, it was one of the best things we could have done for him. He was scared also but it gave him confidence and accountability. It’s called “tough love” and believe me it’s hard as hell and heartbreaking to do that to your child.
