You do not have an anxiety disorder.
I promise you that.
Have you ever looked at people who have a specific phobia such as spiders and snakes and beetroot and thought you luck b******* ... I could easily cope with that. As specific phobias are solved with a few exposures.
Well you are no different.
You have been looking completely in the wrong direction.
You have a small collection of specific phobias.
Fear of relaxation.
Fear of playing
Fear of laughing
Fear of having fun.
Now go and expose yourselves to your specific phobias.
