I really don't want to go back to myself at 14, even if I could know then what I know now, I just don't feel I had a lot of choices back then.
But if I was put magically back in time, with my current wisdom, I would likely stand up for myself a bit more. That might have prevented me some turmoil, but then again wouldn't have strengthened my personality and resolve to stand up for myself... So moot.
