T.B.
My daughter is in the almost the same situation. I put her into girlscouts and that is helping a bit. Getting out with other girls her age is doing wonders for her and our relationship.
I would try to get him to talk to the new dr. Tell him that if he doesnt like him or her after a few visits that you will try to find someone that he approves of. This can be a difficult time for any child to handle. If the ADD meds arent working for him anymore, the dose may need to be adjusted or the medicine changed.
Good luck with this!
