"Sizing up".

This is a small technique I've found to help myself.
I don't like supermarkets, but as where I work has no toilets I have to frequently go up to a busy supermarket to use ones up there.

And this is the technique-
Blindly- I am nervous as heck. This is psychological fear.

So this is the technique I have- I look up- and size up the fear. Reduce the situation down.
What I find is there's an old couple over there, there's a couple of mothers over there, there's a couple of people walking towards the fruit and veg. What's there to be scared of? And that's the sizing up technique.
