I don't know how old you and your sister are - but depending on the state you live in, you could legally declare independence from your parents. (That is, if you are too old for Children's Aid to get involved).

Some states provide you with the income, but also want to know you can work.

This is not because you don't love your mom - but just some support for you two so it might make it easier on her. Maybe there are less drastic legal options that would help you two.

I think that talk is a good idea - prayers it all works out.
