I am 15 years old in 10th grade and I get pretty good grades, but there's something that's been bothering me. Yesterday in health class, we had to practice the Heimlich maneuver on a dummy (and later a baby version), but I couldn't do it. It really surprised my health teacher because I'm the star student of the class..I had an 100 average and everything, but when it came to doing something practically I could just not understand...I don't know, I can't really do a lot of things with my hands (haha), like I'm 15 and I can't tie my shoes, although I've tried hundreds of times, I can't snap my fingers, I don't know how to do push ups, etc. I guess I just don't know, certain things that come to other people instantly just don't come to me. I get high grades in my classes and a lot of my classmates and me to their groups and such because"He's smart", but I don't actually feel smart since I can't do simple things that everyone else can do...does anyone have an explanation for this?
