I have found with
DD who has ADHD and anxiety issues that changing her diet to as low additive as possible has helped with the anger and the Ihate you's. We have been following "Additive Alert" and also read a lot on Failsafe.
It can be heartbreaking I know but you are a wonderful Mum and need to remember that. Good Luck.
