Yes, Emily, you ARE different. In fact I don't know a single person quite like you. Some share the same love for music, or have a good temperament nearly all the time, but I can say without a second thought that you are separate from all others. Everyone is in some way (which I know is a textbook saying), but whether that difference makes us a better person or worse person is what counts. They never care to mention that everyone "being special in their own way" can sometimes be a special on the wrong side of the playing field. The good news is, however, you're all in the right side of the playing field. While you may be far different from me, having different interests and the like, I still hold you as my friend. Differences don't keep us apart, it's just those around you who are missing out by not enjoying you for those differences. You may find you're just not talking to the right people yet if the ones you're around now are causing you to question yourself.
It just gave me some inspiration, and I hope that I don't forget this again.
