I agree with the fear part too
fear of not being good or smart enough etc
which boils down to fear of what others think of me.
When I have that fear,I adjust my behavior to
what "I" think would be acceptable to them.
Then the "world" really controls me.
I get sicker
Today I have nothing to prove to others
because what they think of me is none of my business.
My business is my spiritual condition and helping others.
Then I get "well-er"
