Some anxiety is tied to the need to control:

I want THIS to happen. MY thoughts, ideas, plans are the BEST and / or ONLY way this could possibly work out well. I am SO SCARED that what I want or think should happen– may not. And I am bracing myself to see if they will.

That need for control– is tied to my pride that I know best.

As a Christian that is rooted in the sin of pride. I can turn that over to God when I catch myself caught up in SELF aggrandizing above the will and path of God.
