Help me help my mom

I am extremely humbled to have to ask for help. This is something that I never do. I am trying to help my mother with home care facilities for sudden onset dementia caused after brain surgery . She no longer has the use of her legs, and is declining rapidly . We need to install a new shower which is expensive and need to send her to a rehab facility which costs thousands of dollars that we just don’t have . Our hope is that she won’t need permanent housing and will be able to eventually live normally at home. But as of right now , it’s an extreme struggle to love someone, and not be able to care for them financially.
