Dear Kari
Your letter almost put me to tears. It was so sad. I could feel your frustration in wanting to loose the weight and wanting to play and spend time with your kids. I am experiencing the same problem. I am also from the London Canada area and my doctor is Dr. Mac Leod. My injury was a result of a fall on a patch of ice. (Which I am currently suing the company)
I miss playing tag, and I can't shop for as long (blessing in discuise) my knee just can't take it. I can't run, and walking for more then an hour is killer.
But with all this I try to think about this: it could be worse!
I get sad, but then I am thankful for the privilage of even being able to walk at all, being able to see. Sometimes it works sometimes not. I've posted this comment before and I will recommend it to you. Try yoga (with your doctors approval) You can still loose weight, tighten muscles, you balance will improve, as well as it teaches you relaxation techniques. So when you do experience pain, you will know how to breath properly and to take it one step at a time.
