Thinking about moving

So my mom moved with me Im in a one bedroom she never had her life together always been homeless growing up basically and now she has a mental illness and she can’t live with my siblings cause they have kids etc so she gets ssi and food stamps but she don’t buy food or pay rent now for three months I’ve been struggling like I never have before she moved into my life and I asked my sister who’s in charge of her money that I need some to help out and all she says is no so I’m bouta up and move out the USA so I don’t have to be bothered with them and I was pregnant I lost the baby and they don’t even care they just worried about themselves and I did tell my mom that I’ll accommodate her for a year and move to a bigger place so I can save and move away in a year but she messed up her ssi by calling and telling them she wanna work 😡my sister holding her money for this apartment but now thinking about it like im paying 1400 a month because I have to pay late fees and legal fees once it goes there so moving doesn’t sound right like I haven’t even paid my other bills because I have to pay rent like idk I really don’t and it’s pissing me off
