Hey FJ, sorry to hear things are hard atm hang in there darl you are a great mother!

Just a couple of things that may help - firstly do some research on vitamin therapy - apparently Niacin is really amazing for behaviour... and easier than a diet overhaul

The other thing is just a story about my nephew - he had always been a sullen child - my sis had always had difficulties with him. We just thought that was his personality until he was diagnosed with having double vision - he didn't know any different, so even though he was 8 at the time of diagnosis he didn't tell anyone because he didn't know it wasn't normal!
After corrective surgery he has been a different child - so happy and attentive at school, and co-operative at home!
I guess my point is there could be something going on that you just don't know about.

I hope things get better soon darl
