Am I being selfish?

You all probably know the story, but I'll tell it again for those who don't. My aunt and I moved into a mobile home i own 7 months ago. She moved from a travel trailer. I moved from my moms. My aunt has mobility issues, along with other things. Its ALWAYS something. She just lays in her bed and complains all day. It's driving me insane. I try my best not to go out in the loving quarters when she his, because she wants to talk and talk about how shitty she feels, and how shitty her life is. My mom offered for me to move back to her place. I told my aunt this today, and she was like "what am I supposed to do? I can't take care of myself". I said "if you legitimately believe you can't take care of yourself, then you need to go to a nursing home". She said before that she'll never go to a nursing home. I don't know what else to tell her, and I was just gonna let her figure it out. I know she can, but it'll add a LOT of stress to her life. Am I being an ass?
