Kind of letting things out, because everything is becoming too much for me

My father is here; over the last few months my memories have been coming back of him abusing me when I was a child, though I've known my whole life what he's like. He's here to visit and so I spent yesterday evening with him when he left me stuck in a crowded Chinese restaurant which I can't deal with on a good day (being autistic) yet alone when I'm left alone there. I CAN'T be left alone, I always need someone there to make sure I don't get confused and wander off.
Then I was stuck at his hotel room, where I didn't want to go in the first place. But when he came back he had a beer and he lay down on the bed and made me cuddle him. I elbowed him pretty hard in the ribs and struggled later when he tried to hug me. It's triggers everywhere. I just can't deal with it all
