Helping child understand their Asd

My 9 Year old son is having constant issues with his peers and is at risk of being isolated from them all. He falls out daily and feels victimised . He will scream and shout in their faces and then say “don’t you know I have autism”. He is irrational and the kids are at the point where they don’t want to play with him anymore. This will make him feel worse .I want to help him but don’t know what to do. Can anyone help please ?
