What do I do?

My step mom is visiting for a bit and she asked to stay with me when she does I agreed but asked her to help me do my hair and clean up.
She agrees to this and she comes over.
I specifically ask her to leave my room to me because it's my room and I'm very specific about it.(She keeps calling it OCD i just have autism.)
She "cleaned" my room anyway. (Pushed everything to the side and made my bed.)
I come home from a long day at w*rk to her sleeping naked in my bed my TV is on even tho she wasn't using it, my other TV is plugged in even though it's not being used, bathroom door open with the light on after a specifically said to close the door after using it and to put down the toilet lid and it smells after I told her to spray this scent concealer stuff I have in the toilet before pooping, my favourite blanket and weighted blanket are in the closet because she wanted to make the bed her own and she said she was sick so I let her be but, I kid you not I'm lying on the floor in my closet right now.
I don't know how to confront her about this.
Am I wrong for being upset over it?
