Why Yom Kippur is REALLY the day of atonement

Yesterday was Yom Kippur, the day of atonement, where you supposedly apologize for all the bad things you did in the past year and get a clean slate for the new year. You fast, as a way of making up for your mistakes. Turns out that god wanted to punish me a bit more. I woke up not only hungry, but sick. I spent my Yom Kippur "atoning" for my mistakes by throwing up all day.
