good goofy? or bad goofy?

How do I protect my rediscovery of my goofy free self? It is so easy for me to go back into my head. I let go enjoy then say something to someone or someone reacts a certain way and my old self comes back. I let my brain take over and over think everything and take on all the insecurity thoughts and doubt that I should have been goofy in the first place, that I should have let go as I did. But I should have and it is a good thing I am letting go. Okay I am tired, so I better just stop talking
