Best- oh, my, so much. I think I'd have to say finding this one chat site was the best, as I met several friends there, and also going to London, England, to see one of my best friends who had to move there to become royalty (long story).
Worst- the "down" in my mood cycles, as usual, the depression (which is getting better now, yay) and probably high school, because, y'know, moving schools and being away from everyone I know and all.
