The end of life as I knew it.

Its funny how simply over things can be in a matter of minutes. Its like you walk in a room this one person and leave completely and utterly changed forever. Whether that change be good or bad, it is life altering. Life as I knew it simply walked out of the door with me and went the other way, never hesitating for one second to look back. So that thought leaves me with this one lingering question:... Should I? Because there is no going back. Nothing will simply be as it was. It can never be that way again. So why should I even look back at it? Why waste my time when it was never truly mine to waste in the first place? Life really is over as I knew it oh so well.
