Is there any way to get taller?

Whenever I go to the doctors they say I'm 5'4" (I'm an 18 year old female), and even though that's "average" I still feel realy short. LIke all the celebrities are 5'6" or 5'5" and just that one inch I feel would make me feel so much better. My AP Bio teacher told us about a growth hormone they inject to people to make them taller but they only use it for dwarfs and such. Is there any hope of me getting a little taller?
