Does conscious intent disrupt automatic cognitive processing?

Sometimes I observe that when I reduce conscious interference over my actions, behavioral outcomes seem to optimize automatically through implicit processing. But right now I am totally stuck in a hyper-reflective state trying to top-down control every single cognitive output with my conscious mind and it is making my anxiety go crazy, so I want to understand the neurological mechanism of how our consciousness blocks these automatic implicit processes. I want to completely let go and trust the default mode network or unconscious automaticity, but I keep overthinking the negative clinical outcomes that might happen instead of just faceing them head-on. I wonder how the executive conscious intention actually force yourselfs to inhibit this disruptive over-monitoring when you are overwhelmed by expected outcomes. I would like you to share with me your points of view.
