I have an 8-year-old son who has been difficult to manage since birth. Without us ever hitting him or showing him violent videos, as he grew older, he proved aggressive and offensive. He has a ferocious anger whose origins are unknown, and it explodes when you least expect it, and he rebels against anyone, be it us, his teacher, his grandmother, or the mother of a classmate.
For two years, I've been taking him to a psychiatrist who diagnosed him with emotional dysregulation. But is this really possible? This year, he also took the Wechsler test with his pediatrician, and the diagnosis came back as FIL, which, however, the psychiatrist disagrees with, and neither does the psychologist who sees us parents. According to the psychologist, my son has high cognitive potential, a sort of gifted. That is, the exact opposite of the pediatrician's diagnosis. In any case, he doesn't seem gifted at all, since he has no desire to study and isn't a genius at school.
I need to know if anyone has had similar cases and can help us understand what we're dealing with.
I hope in some help because he’s killing us 
Thank you by my heart
