When ever I feel all sad! I just think to what Buffy said, at the end of season 5 but toi always can go back to the point. The truth behind Buffy, everybody learns this lesson, as the Scoobies say, "The hardest thing to do in this world is live in it."
Based on how I look at things, my life is Hell so there is no way I would disagree with this statement. I really feel that when toi tear everything away toi always have one thing and that thing is what drives toi your life so if your left with nothing toi still have life don't you. So if toi aren't living then what are toi in this world. "The hardest thing to do in this world is to live in it" that is what life comes down to.
