Help with Prosthetic Repairs

I really didn't want to ask for help, but my left prosthetic's lock has broken. I need it repaired and do not have insurance. I do not qualify for any kind of assistance either so I am asking for a tiny little bit of help in getting my prosthetic repaired. I will be forever grateful and thankful to whomever is able to help even a little. My prosthetics are what help me get around and do day to day activities and without them I am very limited.   Thank you!
