Hello
@rosyred, you are welcome here. It's important to deal with this development and also protect yourself. A chat with the GP is a good start as a meds review may help.
There's a Factsheet about this issue and in the hope that you can get some advice from it here's a link to it

I have often seen it advised to have a safe room, with a safe exit, available and keep a phone to hand in case help needs to be summoned.
This may seem like a step too far. However, I have read that it can be useful to report any physical assault to the police as they will record that and this can be useful as a paper trail if you ever seek assistance from Social Services in the future.
If you want to talk it through with anyone the experts on the help line can be good, details as follows
