My son talk in awful way

Hello everyone. This is my first post.
He appears to snap at everything when something isn't quite right, or when I ask him a question, he just speaks in a harsh tone. I don't mean he curses at me, but his voice is harsh and he'll growl.

He's not like this in school, therefore it appears to be how he is at home with me, his father, grandmother, uncle, and a few close friends. 



I'm just so unhappy right now, and to be honest, I'm ashamed of how he can be and how I look to let him to be, but I don't know what to do. [edited by moderator]
