Wow. The first think that jumps out at me is that you are delaying your treatment until after August. That's a long wait. My experience with rehab as a "like 50 year plus female", most of the other people were between 18-23. Most were forced into rehab because of parents or a court order. No one gave a glance at age. You are all in for the same thing. We all learned from each other. Just go in and give it everything you have. Do the homework, go to the meetings and classes, pay attention. And above all, be the model patient. It will get you far.
