You feel it coming on… tunnel vision, sweating, heart racing, and feeling like you are unable to breathe. You need to get away from where you are at that moment, to somewhere different, to do something different, but you are stuck – at work, school, with people, trying to pretend that nothing is happening. Finally, it all starts to calm down. Your heart rate returns to normal, you stop sweating, and then the exhaustion sets in. If only you could stop and rest; if only you could close your eyes for a while.
