One way to ‘get away’ from that place is to direct your mind and your senses to do other things. If your senses are fully occupied you’ll have no time to be stressed.
First things first you should close your eyes. You get a lot of information coming in visually and to be able to control it better you should stop that sensory overload. The next thing that you should do is start focusing on very specific things to do with each sense all at the same time so that you don’t have time to focus on anything else.
With your eyes try and focus on a point in the darkness, with your ears listen to the ringing of your blood, with your touch focus on the air coming in through your nose, down your throat, filling up your lungs and out. This should take your mind away from the situation because your mind is overloaded with trying to do these three things simultaneously and the breathing should slowly relax you.1
