I know how you feel. I used to dance and play volleyball all the time. Now I can't do that. I broke both of my femurs a year ago and the doctor said I can't do my activities anymore because my joints are too weak now where they put the pins in. I tried doing my activities a while back. Even though my legs were strong, my knees buckled, and then hurt for a week. I know how you feel though, if you ever need someone to talk to.
