They ended up fixing my wheelchair yesterday. After a month and a half of my wheelchair not working, I'm finally able to drive it myself. I have gained some independence back and I don't have to rely on others to help get me around places.
Today my nurse and I went for a walk (roll rather) around my block. It was weird being able to do it myself again, but it was a lot of fun. I am hoping that nothing like this happens to me again anytime soon or ever.
