Interesting to hear your stories. Mine is a culmination of little events:
-generation thing
-suicide of a friend in the congregation
-everyone going off to a university except for me
-preaching on stifling hot weekdays in empty trailer parks when we darn well knew no one was home. I said What the heck am I doing out here? Where is everyone my age? Where did everyone go? Why do I feel like I am the only person left in town?
-that song "Landslide" by Fleetwood Mac ("I've been afraid of changes, cause I built my life around you...But time makes you bolder, children get older, I'm getting older too..")
-the disfellowshipping of my little sister. Now "NO ONE puts Baby in a corner!"
