Hi Janet,
I sort of feel the same way as you. We spent $50,000 on my dtr's Residential Treatment Center (RTC)--I was so sure that it was the answer. She had countless hours of outpatient therapy before that, many medications, went to rehab after the Residential Treatment Center (RTC), etc. We did everything we could to help her and I often wonder what would be the results if we had basically done the bare minimum. I'm not sure all the help really did anything except that she can now talk like a therapist and appear to be more "normal." I don't think the "core" person has really changed at all.
I'm not agonizing over it, I also hope that I am wrong, but I do wonder....
Jane
