If, like me, you have many reasons to be less than secure and self-assured, and like me, you are far from stable even on your best days, don't for a moment imagine a psychotherapist will be of more help than a physiotherapist.
I have made so many mistakes, and such really stupid ones, I would start blubbing away if I could remember even half of them. But do not dwell on cock-ups, I say. You don't learn by your mistakes - at least I don't - so best to blunder on making fresh ones.
