best & worst... ?

i can't figure out what the best day of my life has been. i also can't figure out what the worst day of my life has been. maybe they haven't happened yet? but, it seems like they should have happened. i mean, i have to have had one of each because i have lived 21 years of life. is the best day supposed to be the day that i get married..if i get married? or if i ever have kids? what if none of those things ever happen, will i have not had a best day of my life? i have a lot of good days, and great days, and unforgettable days.... but i'm not sure that i can name one particular day as the best... or worst. was the worst when i confessed my love for a boy and got rejected? or when my mom was so disappointed in me that i had terrible cramps and a lump in my throat for more than 36 hours? actually, that never happened, so it can't be a non existent day. was the worst day a day that i was depressed? will the worst day be when someone dies?

do i have to have a best and worst day?
