What height are your parents? It could be that you just haven’t reached your full potential. You are still very young and unless a doctor prescribes something for your height issues, I wouldn’t worry about it. I personally grew 6 inches (15.2 cm) over a summer when I was 15, then continued to grow until I was about 20. Long story, short, dark_sidell out and just enjoy being 17. Go bang a bunch of dark_sidecks.
