Life as a single mom

How do you handle getting divorced as a stay at home mom who has no income or job yet, no childcare and no support. Moving into my moms would be last resort because she absolutely does not want that (I also don’t want to do that to her and she cannot afford it) I’m trying to forget stuff out but it’s really hard when I have no idea where to start. I won’t qualify for anything until I’m divorced correct? I really need out of this highly toxic relationship. Should I speak to a lawyer? Any advice would be greatly appreciated.
