I read this after your first post & thought I had replied.....then didn't see my reply when I read through here again catching up on what has been going on. Remember having internet problems at the time I thought I posted this.
Just wanted to let you know that my thoughts & prayers have been with you all along through this difficult (impossible) time.
I can truly understand your anger with the incompetence that exists, the cracks that are fallen through.....I was there when trying to deal with my Mother & sure understand how much anger builds when we realize how much that is written down isn't followed through on.
Hopefully they will redo the complete neuropsych testing while he's in the hospital. Probably a good idea for your grandson to go to another school at this point....at least he won't have the past haunting him & can maybe if they get him on meds that work, start afresh in the new school. Hopefully a school that will follow through on what they promise.
I have an acquaintance here (through a friend) who has a son that needed to be in a special school.....strangely, they couldn't find one in the United States that could provide the care that he needed & not sure if it was in Puerto Rico or Costa Rica where he spent years in school with trips home & trips there to visit. He just turned 18 & came back to the US....know that he still needs special care a still isn't able to control the outbreaks that tend to occur.
Hope that the testing will be able to show up something concrete that can be treated.
Will keep your grandson, you & your whole family in my prayers.
