Welcome to icliniq.com.
You seem to have gained a lot of weight for your age. This is one of the major reason for not growing taller.
Children who are overweight are often seen to stop growing taller earlier than others and this is particularly true for girls.
Also, you may have acquired your mother's genes in terms of height.
The good part is you still have a few years to go before you stop attaining height.
You should see a dietician for a protein-rich diet and you must lose weight.
Also get a lot of exercises including stretching exercises and also skipping.
Yoga can do wonders too if done properly.
