Help Novlett through her foot surgery

Hello i'm Jerry i'm 18 years old and i would like to ask everyone to please listen to my story and my goal to helping my mother through this endeavour. My mother has been having foot problems for over a year, she works as a nurse with minimum salary, and ever since last month her feet has been getting worse and worse, she still couldn't stop working because its only me and her and she needed to work to get income to pay the bills and to put food on the table,i work full time at a restaurant to help my mom with the bills but ever since last week when she came home from work and headed straight to the bed,i asked her what was wrong and she told me her feet was hurting really badly, ever since last week my mom hasn't been able to walk on her feet, my uncle took her to the hospital and the doctors told her that in order to fix her problem which she found out was a severe case of Arthritic damage to the joints of her feet and her knee's and its gotten worse because of her working. the doctor said that its best if they perform surgery on her else soon she'll become disabled. my mom doesn't have health insurance and the only person that can help her with the cost of her surgery is me, my uncle is her only family left and he doesn't the money to help her, the cost estimate to about 50,000$ in total for knee and . Any amount of donation is very much appreciated, her surgery is in a week, ill be working overtime to make as much as i can to help pay her medical bill. Thank you for listening and for your support.
