Good Medical Out Of Reach

I am 20 years old and a serious sports person. I recently damaged my knee and now need an emergancy operation which is very expensive in my country South Africa. Our goverment hospitals are in such shambles that I am so scared not coming out alive. I cant work currently because my job is a standing, walking and driving posision none what I can do at this point in time. I get paid only if I work and therefor I cant earn my wages. My mom is an only parent and dont have a medical aid because she can not aford it. Any small donation will help.
