It sure sucked to be Buffy.  Not only was she in trouble at school for saving the world, but her vampire boyfriend lost his soul and turned evil and kept trying to kill her.  Sucks, right.  At the end of Season 2, Angel opened a portal to a hell dimension to destroy the world.  In Buffy’s most defining moment, the Slayer plunged a sword through the love of her life, sending him to the hell dimension, saving the world.  The challenge was, the evil Angel had turned good again at the last second.  And Buffy still sacrificed him to save the world.  That sucks.
