Help my grandmother live again

Hello I’m Tiana and I’m trying to raise money to get my grandmother a stairlift. My grandmother sadly lost her leg last year and has been struggling to walk ever since. She has a prosthetic leg but her remaining leg is also failing her now. She can no longer walk up and down the stairs without excruciating pain. I hate seeing my grandma struggle like this.

She’s always been there for me my entire life. She has undergone multiple surgeries and treatments to just have more time with me. I want to do something for her. If you could help it would be very much appreciated. Thank you so much.
