Here are a few identifiers that I am not feeling well:

• Haven't updated twitter in 24 hours
• Haven't hit the 'refresh all' button on my podcasts in 48 hours.
• Slept more than 10 hours for more than one day in a row.
• Gather 4 or 5 people around me. Am I being funny, interesting, or at least loud? BINGO. Somethings wrong.

For the past few days I've been what friends and coworkers have heard me call, "crazy". I've been quiet, needed incredible amounts of sleep, and am constantly confused about where exactly I am (and possibly what has happened recently). Here's a bit of explanation.

While I understand that self-diagnosis can be dangerous, Melissa and I have come to the conclusion that what I may have is Depersonalization Disorder. It's usually brought on by large amounts of stress, or by switching up my social surroundings drastically.

If you see me like this, there isn't much to worry about. Other than a bit of social awkwardness there hasn't been anything detrimental caused by my bouts with DPD. I've successfully navigated trans-atlantic flights, performed various work tasks (although with admitted lack of focus) while going through these semi-irregular periods. Asking me if I'm OK isn't super helpful here either, because I'm not, but there isn't a constructive way to tell you that.

What I would appreciate is a little extra understanding. My teammates are incredible examples of this: taxi-ing me around London, responding to my wife's frantic messages wondering if I'm still alive, letting me sleep for 24 hours straight through the weekend so that I can recover for next weeks work, etc.

I might ask you about things that happened in the past 1 to 48 hours, or I might just ask for confirmation of our current location. Think of it like re-checking your phone for the time every few seconds when you are late for a meeting. It's not that I don't know, I just want to be sure.
