Where the heck did my motivation go?

I used to be the most productive person on the face of the planet. I manage an entire state, I manage my daughter, I ride my bike ALL THE TIME, I kept up on the yard work, walked the dog constantly, got all of my reports in on time, never complained…..What the hell happend? I can’t find the want or motivation to do simple things that will keep me employed let alone head to a work event with a smile on my face. Am I just burned out or did I loose my motivation with my last bag of luggage? I’ve looked all over for it.
