Yes, I do know CBT very well. It is much more than people generally think. They think it is easy, but it isn't. Neither is it an old-fashioned method that was only used in the 70-ties and 80-ties. It has grown and is still in development.

I have found out (by my GP) that I have physical disease (not dangerous for the time being). That physical disease makes me tired.

I feel more relaxed now when I know that my tiredness is physical and that I will become slowly better as time goes.
Not only that, but I will not be 100 % well before my vacation, but still well enough to enjoy my vacation.

I will continue with CBT and the meds for my physical disease.

Thank you Moose!
