It's been so hard lately

I just wanted to vent. My 9 year old (level 2) is going back to school today after his 2 and a half week break. His whole break was so hard for all of us (him and our family). Any change in routine is super difficult for him. Anyway, it was a living hell. He doesn't get along with his 4 year old NT brother at all and constantly hits, spits and yells at him. Our extended family visited us and he got an ear infection while they were here which made everything harder. (His infection is cleared up now.) It's been so hard to get him to do even basic hygiene lately. I know it is not his fault he's this way because he's autustic but I am just so mentally exhausted. Everything seems like such a struggle with him, it is just so tiring. I love him so much but at the same time he makes me so tired. Anyway, thanks for letting me vent. Hope everyone is well.
