My mother in law

This is Esther, better known as mama Ada in her village in Cameroon. She is my mother in law and is an active member of the community and an extremely generous lady who is always ready to help those around her. My husband (her son) and myself have managed to bring her to France in order to get treatment in order for her to be as independent as possible in her own home. Treatments are terribly expensive and we have already managed to cover all the preliminary exams, but in order for her to be able to continue living alone, fetching her water and cultivating the little land she owns, she would need a knee prosthetic. The operation costs 20.000 euros and although that seems like a small amount in the grand scheme of things, we unfortunately do not have that kind of money. We would be grateful for any amount that would help Mama Ada to be able to walk independently again and live the life she deserves.
