Gloria's Prosthetic limb needs changing

My name is Gloria Okonofua and I’m Nigeria studying anatomy at the university of medical science ondo state - I am an amputee. My right leg got amputated when I was 7 years old after being involved in a car accident. I’ve been using a prosthetic limb which I often change every year. I have had my current prosthetic limb for about 3 years now and it’s totally worn out and has given me sores and injuries each time I wear it , making it almost impossible for me to walk and do my daily activities and even school life. I am soliciting for help so that I can get a new limb that will enable me walk  and do my daily activities. It is affecting the quality of life I have, - physically and emotionally. Please help!
