I've got a few problems as see I come from a?

dysfunctional family and see my mother is living with my brother as she had a nervous breakdown a long time ago and see she just gave up on life and just tells lies about moving out all the time, and it's started to have an effect on me and my brother as she wont look to sort things out for herself. And I don't know what to do as my brother deserves a life, not to have her clinging on to him, as he's got a daughter to look after!!! And I need my space as I'm 27 and just trying to find my way in the world - but she wont look to go into shared accommodation at all or pay off her arrears to get her name back on the list as she Just keeps on lying to us both but at the same time I don't wanna see her homeless and yesterday we had an argument and some of her stuff was thrown out and she burst out crying, what do I do? As nothing ever gets sorted out, it just goes on and on, and on - never getting any better for this family!!! I sat for an hour in silence yesterday after I had finished crying - worried about it all!!! We've tried to help her but she wont listen at all, and our other older brother is against us trying to help her as he spent money that she had saved up - and pretends to be helping her but he;s not at all as he's not a good person and favors people outside of this family to this family!!! What do I do? As I just wanna see things get better!!!
