I'm nearly 20 and I'm that height. There's only down from here I'm afraid. I'm not a fan of high heels but I do like platform shoes, they add a good couple inches to your height and feel natural to walk in, so maybe buy a pair of those since you can find them in every style everywhere now.
Also, master the art of swiftly climbing furniture. The number of times I've clumsily fallen off my desk trying to reach my top shelf is embarrassing.
