My son is 7 and is just about to get an assessment through cahms for adhd. However he has so much hate and anger towards me I feel like me breathing is a burden to him. He visits his dads every weekend they have a lot of money big houses etc and then when he returns to me to my small flat I’m starting to think because of the big difference he doesn’t want to be here with me and prefers his dad and his side over me. Do you think this is the issue? Or is anger part of adhd? The things he says to me is like he resents me.
