I am anxious about how others might perceive me.

Dwelling too much on what others might think of me comes from the belief that I am special so I need to be perceived as such. 
We are no more special than a clump of grass on the side of the road.
How others perceive you is simply their thought, over which you have no control.
Let go of the belief that you are special, and you will be able to enjoy your life much more.
