To me for your age, your height appears normal. do not develop a feeling of inferiority over your height. concentrate on your positives, gain confidence, develop a personality . Conquer your friend with your personality, confidence, wit, inteligence, some great personalities in life like Napolean were not tall but see how they conquered and ruled nations. </p>
Coming back to your actual question. maintain a healthy lifestyle, eat healthy , do physical exercises and see a doctor to findout if there are any hormonal problems that are hindering (if at all) your growth. </p>
Cheer up buddy do not worry about what you do not have, use the positives that god has blessed you with to rule the world.
