Not knowing who you will find in the mirror each morning can be exhausting (on the down days), and exhilerating (on the up days). Ride it out, Nessa, just a moment at a time. I woke up to feeling like I have the flu and I don't i just get really intense body pains when i have any kind of a shift and I was in "overdrive" for a couple of days so I knew the crash was coming. It IS exhausting though. If you are at work, you can always go hide in the bathroom for a bit if you need to. If you are at home, distract yourself and try to get outdoors for a walk.
