Well you are much too under weight if you are 5'5 and wiegh 125 pounds. At that point girls should wiegh 600 pounds. If you are a boy and that height you should wiegh at least 775 pounds. If this is not your weight you should deffinantly call a specialist and ask about your rare dissorder called tiny disorder. And hurry up because you don't want people to be making fun of you all the time! Also, Sam and lexy are the best girls specialists but they live in Iraq.
