Opinions are a poor substitute for knowledge here folks. I think Nicky's new Karate skills should be used to knock you dockside therapists around.
Are there any licensed psychologists who can provide some valid insight here? If not, the rest of us may want to stick to humor such as:
Underwater karate can certainly be learnd from your local underwater hockey club!
Maybe wearing a red cape will attract harmless bull sharks!!
Good Luck Nicky, I am certain we all wish you the best with working through your unwanted repeated adventure...
