Would I be wrong? Please give advice.?

My mother has cancer and is living with me. I live in a 2 bedroom apartment with an 8 month old and an 8 year old children. There is no other room in the apartment. I am a student fulltime and work part time. My mother is enrolled with hospice. She has been getting worse for the last couple of months. She had 2 surgeries to remove some of the cancer in her liver to prolong her life but it seems to have made her worse. She can do for herself but she wont. I cant even get her to take a bath (please no ewww or make fun) I am the only child (25) and the only other family is my aunt who has a 4 bedroom house. She wont help me with finding my mom a better living enviornment. Would I be wrong to place her in an isted living facility? I want her to live with me, but I only have a small 2 bedroom and no money to move to a bigger place. I make sure she gets her meds but thats all I can do, having 2 young kids myself. She has medicare. Is isted living the best, or will I be wrong to do this
