Hi Frazzlepop
Sorry to hear things still very challenging for you… your mum is probably in denial or minimising how serious the situation is to stay sane. I am guilty of the same
I really feel for you, and your disabled brother who doesn’t have the voice needed to get safe. I hope you can get the NMO and occupational order I’m sure you can do it in your own name and on behalf of/for the safety of your disabled brother.
Might be worth seeking advice from domestic violence organisations like women’s aid…for both you and your family.
I really hope you find peace soon
