I would focus more on your confidence rather then growing spells. I agree with the other posts, you are still growing so you may still gain some height, also finding shoes you like that give some lift is always an option, but no matter if you are 4 feet or 6 feet, if you have the confidence in yourself and don't focus on that bringing you down people won't see it anymore as something to pick on you about. There are some good meditation skills to develop to help you clear your one and find more confidence. Overall how you carry yourself day to day can make a big difference. It's just finding that strength that's the hard part.
