Recovering peace and serenity

An unexpected and surprising result of my trip to Chicago was a feeling of serenity that lasted almost to the end of my work shift today.  It could have been leaving all my daily struggles behind, the day relaxing on the beach,  or exploring the city that provided me with a sense of peace.  A wonderful feeling, one that I am going to try to nurture.  Just five minutes before I was due to clock out, my coworker caused me to feel stress. She was making copies of employment applications, discussing the new branch store and talking about a potential firing.  All subjects that cause me anxiety.  I am feeling manipulated into working the branch store.  I am trying to recover the sense of peace and serenity.  I know I can do it.
