Right? All mental. My new fear is words that start with “n” and it all manifested because I thought to myself “man, N words like the word neurological are SO easy for me to say.” One thought led to another, and a month later I know hesitate or stutter on words that start with “n”. I have literally rewired my brain to be afraid of “N” words. Which means it can be rewired to fear no word. That’s a fact.
