Sometimes, when I'm thinking or stressed out, I stop breathing. I guess it's a form of apnea, but it apparently doesn't happen in my sleep (at least, not enough to warrant a diagnosis).
Sometimes, I let things get out of hand. I pack my schedule; I rush from pillar to post. It's exhausting.
In five weeks I will be on summer vacation again. The next two weeks are insane (much like the last two). I have some things jammed into my summer already, including a family wedding, some professional development, and a road trip.
I just hope I remember to breathe.
