I'm beginning to regret agreeing to spend the whole weekend at my mother's, staying Saturday night with a neighbour.

Last week it felt a fine idea - meaning my sister would feel free not to go there for the whole weekend.

Of course my mother has a carer. But she doesn't want care. She wants company. The company of one of her two "children".

Why should the prospect of this simple two day stay upset me so much? I am still so screwed up. I want to scream.
