I don't know how I'm going to live at this height forever. What other options are there to grow?

I'm 15 and just under 4'9'', maybe less. I am not a "little person" (midget), I have somewhat short legs but otherwise appear normal and have a proportional body, and am healthy. I had an X-ray done on my wrist and the doctor said I can't grow anymore but she is referring me to an endocrinologist. If I can't grow anymore, why am I being sent to an endocrinologist? Being this height is destroying my self esteem and when I walk into a room, if I'm not wearing atleast 4 inch footwear, I seriously feel like dying. I need some help...advice, if its possible to grow, what an endocrinologist might be able to help me with.
