I learned to deal with moments of hightened anxiety by taking it as a signal for me to ‘do something’. That usually involved one or more of – going for a walk, picking up a guitar if nearby, putting some music on, messaging a friend, making plans, making something nice to eat, etc. just simple easy activities, and usually it releives the anxiety. Before that I would just let the anxious feelings mount up and not really know what to do or know why I was feeling that way… which made me more anxious..
