Don't kick yourself over this. I doubt anything is wrong with your brain Kirsten. Stress & worry can play tricks on your mind. I have forgotten
my email password before but I had the luxury of being at home at the time were I could just look it up in a notebook. If I was in public, it would
be at lot more embarrassing. Sometimes the more you try to remember something, the harder it becomes, but the minute you stop trying so hard,
it will pop back into your mind. You are just human like everyone else.
