I personally have always used ‘a little bit of this’ ‘a little bit of that’ but never totally followed anything.

The one time I had therapy that was pretty much the model she followed with me, there was some CBT involved, but no work book, some suggested reading but nothing compulsory. It worked well with me, although I wasn’t in a very deep depression it must be said, but I did have some unhelpful thought patterns and needed to talk through a lot of stuff. In my case just having that right person there to listen and question was the key.

I think what works for some will work less well for others, it’s finding the best fit. That can change over time too.
