How many times have we felt out of sorts, felt overwhelmed, or felt like something wasn’t quite right? How many times in our lives have we lost sleep, and woken up in the middle of the night in a cold sweat, worrying about the various upcoming events in our lives, in the near or far future, and then analysing every little detail of what could possibly go wrong? How many times have we felt that inexplicable and seemingly inescapable feeling of dread, anxiety, apprehension and sense of uncertainty, sure that nothing on earth can shake our concerns, and sure that we will take our thoughts and feelings to our grave? How many times have we believed things to be true, when we know in our hearts that they aren’t? Is the answer more than 10? More than 100?
