No problem, glad to be able to offer some sound advice. Now if i can offer you some advice from my hypnotherapy. Next time you get a troubling thought imagine the thought as a solid tangible object that you put in your hand, after you have it in your hand just let go of it, drop it out the window, throw it as far as you can or flush it down the toilet. Remember it is your thought, it's yours, you have a hold of it, so you can just as easy let go of it. If that's a bit too alternative therapy for you then just tell yourself that it's only a thought and a thought never did any harm to anyone. Good luck.
