I feel for ya. I went ahead and made varsity football while growing only to 5'3" my senior year (I was a mean lil bastard). When I went to college, I stopped lifting weights and started drinking the hard stuff (beer didn't get me there quick enough for me). By the time I was a Junior in college, I grew to 5'11". I finally topped off at 6'.
My parent made me take Cotillion when I was in junior high (Cotillion is learning ballroom dancing, what to wear-formal, informal, how to eat - what fork, when - basically how to be a gentleman/lady). I had a crush on a girl a year younger than me. I asked her to the Cotillion formal and she said yes. However, when we were posing for pictures, I was the one who had to stand
two stairs up on the staircase while she was standing on the floor beside me.
The best advice is to look at your parents' family. Are they all short? You've had better diet, health care and nutrition, so you should be an inch or two taller than your dad.
[EDIT:] A doctor friend of mine just told me your bones don't stop growing or thickening until you are 30-32 (white guys w/ european heritage). So drink your milk!
