Wei Friend,
What your brief synopsis described sounds exactly like our son. However, in his case, it was Non-Verbal Learning Disorder. I'm not sure which, if any umbrella it falls under. However, it made Elementary and Middle School miserable for him, that's that's the bad news. The good news is he grew out of it and is now socially normal, well, except he like bikes. Don't take any diagnosis at face value, dig into it and question it.
I'm relating this because it is absolutely impossible to get a diagnosis over the internet, and you need a real one, so you can advocate for your son and help him prepare for life. If you have ANY doubts about the diagnosis, get another one. Most school districts will either facilitate or provide one. They are often also a good resource for competent practitioners who can help if needed. PM me if you need anything.
