It's true. Life is a fickle, fickle fiend.
An update: my mission has been postponed.
A few weeks ago, when a mission call should have been sent to me, a letter got sent to my stake president instead. There were a bit of health struggles a little while ago (I'm not dying!) and the brethren feel as though we need a bit more time to pass to make sure I can continue to be a successful, healthy little missionary before they send me half way around the world/country/state. I can reapply in May.
Surprised? A little. Disappointed? Yes. Sad? Definitely. Discouraged? No way.
I will still continue to prepare and plan for a mission! I just have eight more months to do it.
Thanks to all (Josh and Susan! ...and Nicole!) for the wonderful support and encouragement. This is not the end, merely a 'To Be Continued..."
