This actually looks like the ground work for cognitive behavioural therapy. The idea (grossly simplified) is to take those observations of negative thoughts and build a rational response to those thoughts (cognitive part). Then you build a habit of noticing those thoughts and responding with the rational response. It’s far easier said than done, and perhaps best dispensed by a therapist. But these mental tools have been crucial to improving my own mental health. Some great books on that go into more depth than I ever could include Feeling Good by Burns or Byrne, Overcoming Anxiety and Overcoming Depression.
