Any social workers out there?

My mom is currently hospitalized for attempting suicide. She is "homeless" because she left her home where her 15 year old son was threatening to kill her. I can't take her in because we have a new baby and my relationship with her has never been great. I feel so guilty about not having her live with us, but it just isn't a healthy choice. Anyway, she said the social worker at the hospital will help find her a place to live. But I am worried she will end up in like a half-way house or something. Does anyone know what type of housing they would find for her? She doesn't have a job right now.
