I need some help with regards to my mums behavior as of late

I will go into brief background. we are going through a child custody case. My daughter was removed from my care because I reported child abuse. She also disclosed to professionals. Long story but Social Services are saying i am a risk because i made a complaint against them for failing to protect my daughter when my ex ran off with her. My council ignored my concerns, but was returned a year later by another council for one of the concerns i reported and now have hard evidence that they are covering up child abuse.

I have called my mum as a witness as my mum also heard disclosures. My mum has started becoming very aggressive, she barged into my bedroom while i was asleep shouting abuse at me, shouted at friends etc threw a cup at my friend for no reason at all. This is totally out of character but lasted about a week. She has been moody but this is the worst, becoming violent.

I am trying to get my business back up and running but when on phone she will shout in background, without reason. I have also been on phone seeking legal advice and she has shouted in background

I dont know what this is or what to do but her shouting is making me boil up

Basically i lost my house so been living back with parents and cant get another house
