I wasn't down because I wasn't popular. It never really affected me at all. I had friends and that's all that matters. People knew me, but only because I did favors for people all the time. But I wasn't popular by any means. I just remained myself.
Four years of popularity is like fifteen minutes of fame. You went in to high school a nobody (if you're popular between coming and going, good for you...) and you'll leave high school a nobody. When you go to college or to find a job, nobody's gonna care about how popular you were in high school. Hell, I don't care about how popular celebrities are, let alone somebody who was well known in a school.
