I'm Broken, Again

So, last August I hurt my back (to read about it, click HERE). Well, today it happened again. I was walking around my classroom, checking on students when all of a sudden my back tightened, I got dizzy, and almost passed out. Why would this happen to me? WHY!?! Again, it is a horrible time for me to be having back problems - I leave on Saturday for a 10 day vacation down South (more info, click HERE). Last time I was miraculously healed. Lesli said it was because of my great faith. Well, hopefully we have a repeat performance.
