Moving out

So I had incident a while back with my mum trying to kick me out and such. I’ve had issues with my mum that was physical,verbal, and sexual not once did she apologise,I couldn’t stand it anymore.So an incident happened today, where my dad said my mum could do anything but I would still have to forgive her,I’ve already been telling everyone I’m scared of her and having hallucinations of her strangling me to death.

I called my grandma begging her to let me stay at her house for a couple of days.Now this shocked my mum and dad,they didn’t think them trying to convince me to make up with my mum would result me in leaving. Mind you my mum is trying to apologise but I do not believe it for one second she means it,my dads here begging me not leave my mum is wondering what she did wrong. I’ve explained my story so many times I’ve cried for at least someone to save me from this abuse.None has worked and I’m exhausted right now I’ve never felt more tired of this. I don’t know if should I listen to my dad and stay,leave for a couple of days,or leave permanently.I need help deciding what to do
