Medical care and home assistance for Lisa

As many of you know my sister is intellectually disabled and needs 24/7 care. You might also be aware that my mother is battling cancer, and I am trying to care for both of them. It’s becoming more and more difficult to ensure the necessities of their care while working and having the trials and tribulations of a new business. 
The medical care and attention needed is taking a toll on all three of us. 
The most difficult part is my sister doesn’t understand what is happening with our mom and equates sickness with death, as our father died when we were teenagers. 
My mother is not doing well and my sister cannot take care of herself because of her disabilities. I am hoping to raise money to put towards my sisters daily needs, as we struggle with the perils of life.
