Chocorua is right, I did not find it offensive. I understand that you do have a lot of physical limitations. Reframing how we think about those limitations can help us to cope with them and help work through the causes with a clearer mind. It was not my intent to single you out, either. I see this sort of negative thinking a lot. I also have seen, both in myself and others, how much we can change on the physical level by changing how we think about a problem.
