I wonder if you are taking treatment for Hypothyroidism as a part of self medication or you consulted a Physician. You are 17 years old. You have another 2-3 years during which you may grow further. Please consult a General Physician in your area for a physical examination, thorough investigations and proper treatment. Hypothyroidism is not the only cause for short stature.

Delayed treatment for hypothyroidism may have an indirect effect on growth.Consult a endocrinologist in your area for appropriate treatment

Endocrinologist concern required.

Thyroid replacement therapy doesn't cause stunted growth. It promotes growth hormone secretion.majority of  growth hormone is released during deep sleep. Aim for 8 to10 hours of quality rest per night. Take at least 20g of protein per meal also Calcium and Vit D.
