Idk, the first thing that comes to mind is doing the mile run in grade school, and trying to complete it fast enough to be able to win the Presidential Metal of Honor. I won it every year. This time I made it just in time (though the coach was counting down the seconds as I was running toward the finish, and the last second was like 1 or 2, so I wonder if I really did make it on time or if he was just being nice), and I was breathing so hard the coach asked me if I had asthma. I've never been good at running. If I run for too long it starts to feel like something's wrong with my blood, like there's not enough oxygen in it or something.

I've also been in some pretty exhausting mental situations while being psychotic. Once my mind was so busy and stressed I sort of fell against the wall as I was walking down the hall. Then an ambulance arrived at the house and asked if anybody had called, the weird thing is nobody had.
