It's none of my business really, but I'm not coping very well under the shadow of a terrifying bullying and increasingly violent brother who is in absolute denial about his situation. He is married with stepchildren and a child of his own, and the relationship which has, as far as I have known, always been on dubious grounds. Now it's in freefall, and it reminds me of my own childhood, which was fraught with terror. It was so so black, and only started to be less terrifying when I was about 25. My head is spinning and it's as though the whole thing is starting up again, although time has passed and the darkness will lift. It is so so black and frightening. My father is in denial too and older and madder than ever.
