My brother has a history of mental health issues. He was admitted to a mental ward several times years ago and diagnosed with schizophrenia, although we have since all thought he has autism (which lead to psychotic episodes). In recent years he became abusive, especially to my mother. If you disagree with anything he says he'll berate you into saying he's right, and even if you do agree he'll still find something to argue with you about.
Every Christmas we try to make sure there's a group of people around him so no one gets stuck alone with him, but this year he took offense to "the fire being too hot" just after my other brother had gone and shoved my mother before storming out to stay at the b&b round the corner.
I begged her to come stay at mine which is 20 mins drive away, but she stayed in and turned all the lights off, telling him she had gone to mine. He messaged us both abuse all night then went round to hers in the morning and pushed her to the floor, hitting her 10-15 times. She rung me saying she would call the police, then he turned up again crying but also saying she'd made him do it and she got a neighbour over. With the neighbour there he didn't return, then me and my partner got there and I stayed with her whilst she rung the police.
They came to see her that evening and my brother has been told he can't contact her for now or he'll be arrested. He has messaged me saying he was 'ill and drunk' but sounding remorseful. I have not rung him back.
I'm now constantly worried about my mother (rightly so) and checking in on her lots. She says she is willing prosecute him, which I agree with. It's very hard emotionally to deal with it all (as it is for mum) as I feel both scared and sad for him, that he needs help. We told the doctors he was threatening us and they did nothing. I will feel better once they admit him to hospital, but nothing has happened so far.
I should also mention I had another brother who passed away 10 years ago, so this is especially hard on my mother and me because we want to help my older brother like we couldn't help the one who went.
Sorry for the long blurt, but I've been thinking I need to write all this down to help my anxiety, which had reached new heights.
