I know this thread is older/resolved, but I just want to throw this out there because I've met a lot of taller girls who were self conscious about their height: TALL DOES NOT EQUAL AWKWARD!
Own it! It makes you stand out and it's actually something a lot of shorter girls envy. Some (actually, a lot) of the most beautiful girls I know are very tall. I can definitely say I have never looked at a taller girl and thought that her height took away from her appearance or that she would look better if she were shorter. Vice versa, same goes for short girls, btw.
