TRy to accept, and move to on with your life. My daughter is 16 and is only 4'8" too, and she know she won't grow one more single inch! There was a time where she didn't accept it too. That was when all her friends suddenly started growing, where she did NOT. We asked for x-rays then to know how tall she would get. The answer was short and hard: no more growing !!
That day she reacted very mature . "Okay," she said, " from now on, my pants will never get to short anymore!"
She never again complained about it. Her boyfriend is at least 1 full head taller, and he says she is "very cute"
