Hiya... this sounds a bit like my 10yo DSS...
Does any of this this sound familiar too?
Can't / won't listen, extremely loud, flaps arms around, makes weird and unpleasant noises, often grumpy, doesn't like himself, doesn't quite "fit in", disobedient, steals and overeats food, snatches things that he wants from others, talks incessantly, talks in a booming voice, interrupts conversations, talks in a mean way to younger siblings, creative thinking, struggles to focus, struggles to lose at a game, often jealous, often inappropriate, often won't make eye contact, genuinely doesn't understand if he's done something wrong, daytime and nightime wetting, occasional soiling, swearing, "awkward" movement, creative storytelling, takes a very long time to explain things.
I'm 100% convinced it's ADHD. Doctor won't diagnose though. Possibly your son might have it too?
