Im tired already i dont know what to do

I have two children my youngest has autism, im having hard time doing the chores at home and having patiences with his naughtiness like taking my thing from my office table(im working at home) and wearing all the shoes in the shoe rack and sometime he doesnt want to eat. My oldest is 10 and gives me a snobby look when i try to give her a chore i really get upset and burst into anger if everything is in a mess, get tired and frustrated. I cant do this anymore what shall i do #momfustrated #momtired ##advicepls
