It could perpetuate it, but focussing on triggers and negative cycles isn't very positive. Mental disorders are like prisons that need to be broken out of...getting on with your life in spite of the ringing. I'm only suggesting.
Breaking the thought cycle of these symptoms is very important. Your mind has triggered these symptoms, tell yourself that they are not real. Tell yourself that they well soon subside.
You are what you think - clear your mind and focus on something productive that you enjoy doing.
