Their many ways to get taller. Some are rather medeval and I would not recommend them. If you have a real concern talk to your Doctor. Their are surgical procedures and or drugs that can help. For most people they grow out of it. Involve yourself in sports that require you to stretch such as basketball. I think it's more important to develop your personality. People care about that rather than how tall you are. Or I guess you could hang upside down for a while ;)
There is still a possibility that you might get taller. But it has to be in young stages of your life. As in, not older than 18. Play a variety of sports, like volleyball or basketball, and also eating healthy and drinking plenty of water helps. Good luck.
