No logic in self diagnosis.

Scenario: I am watching a Netflix show. Tension builds up in the legal drama. I quickly close that screen and start playing Solitaire

Diagnosis: Why on earth am I so stressed by unfortunate events taking place on screen? Based on an article on behaviour of people who read the end of the book before the events in it, it appears that I am anxious.

Therapy: I did not read any article on therapy for anxiety. I don't know what to do.

Question: I have found security through hard work and by making tough life choices. There is no one or nothing to stop me from living a productive and mildly adventuresome life. So why I am still anxious???????????????????????????????????????????????????????
