We are geared to live with a level of fear; our bodies, and minds, do all sorts of intersting things when we are frightened or stressed. Millions of years of evolution churning into action, driven by our funny little brain boxes. Being perpetually under the pump is not good for us, so the survival instinct kicks in and, eventually, we develop a bit of imunity and don't react as strongly when we think of the threat. Being scared, though, is very sensible because the threat doesn't ever go away (sorry) You will find it drops off your radar for days/weeks/ months at a time. Deep breathes.keep plodding. Mxx
