A couple of times a week (but sometimes more) I have this problem where my mood very suddenly changes. I can be feeling quite ok and then over half an hour or so I feel it changing. I then feel desperate to get away from where I am and that I want to hide in a dark place, get away from any people, somewhat anxious, stop focusing my eyes, and extremely tired. Unless I can sleep (even for just 10 minutes) it stays with me usually for hours. And it is awful.
I can't identify any particular trigger, or why it happens some days and not others. And I don't really feel that my senses are being overwhelmed as such leading up to it. Maybe its an accumulative thing though.
It feels like it has very clear edges - its either happening to me or its not. And my skill levels are greatly affected when it is.
Anyone else relate?
