((((((((((((((((((((((((( granite ))))))))))))))))))))))))) I have been in just this place. T1 was very big on cognitive distortions, tried twice to get me to keep a journal of them and twice I ended up going ballistic. I felt I was being asked to document the fact that every reaction I had was wrong and I wouldn't know the truth about any given situation if it came up and bit me. I didn't believe that and couldn't go on with it. Challenging the validity of ALL of your very thoughts, at every turn, is frightening and infuriating at same time.

You have the right to tell yr T this, and you don't HAVE to do any exercise you're given, if it doesn't feel right to you.

Having said all that, I will climb down off my soapbox and say that I do recognize the existence of cognitive distortions. There are a lot of people here on PC who worked through them and found great benefit in it.
hugs to you
