Amazing Jara! I did not see any technical errors, even upon rereading it. so good job on that. as far as taking out some of the words, even though this length should not be a problem, i would say you should cut on the description of the man
In that hospital room, amongst the drab curtains, boring furniture, seeing him on the bed- this was my epiphany. This was what I felt the need to prevent; this was my future. It took a fragile man who lost one arm, a cold January evening, and a street in Downtown Toronto for me to realize the increasing problems in current prosthetics.
This is a growing problem in our society, and when I first met the man that cold January evening, I did not foresee the awareness I would grow concerning prosthetics.
i would find a way to cut down one of these three sentences, which should take care of the length. you can either combine the first and the third sentences into one concise statement..or eliminate the third sentence on the whole because you have already stressed the importance of the amputee in arising your concerns with prosthetics in the other parts of the essay
good luck
