Is he on medication? Does it need to be adjusted if he is? Are there any activities he likes to do outside the house?
This summer I had mostly the same stuff with my 7 year old. ADHD- inattentiveness not hyperactivity. What I did find is when I started talking to the doctor and adjusting the meds, he stopped yelling so much. My boy loves baseball and art. When enrolled in a program that keeps him away from me and happy and enjoying other kids company (as much as is possible for him)he's happier.
I've also been reading parenting books for tips and suggestions. I really like "Scream free Parenting"...I think you can find it at Target.
Lastly, be careful of his diet. I know my boy is much worse when he has had a lot of high fructose corn syrup and red and blue dyes. Nutrasweet also tends to send him into rages. My boy like yours I'm sure is bright and funny, but these challenges are just exhausting. Keep up the good work!
