It's not to do with confidence, my co-ordination is just poor. I can't catch a basketball successfully. My brain lags, I duck when I shouldn't, and misjudge everything. I can't play sports because of it, and no amount of practice will solve it until I stop growing and my brain can adjust to my size, cause it thinks I am shorter, and over compensates, meaning I think I can reach things that I can't, and thinking I will hit something that I won't.
