I Overthink and Overanalyze Things

I did that too a lot. And even now, so many years later, I still may overthink. For me it turned to be caused by fear. Fear of having messed up, fear of doing or saying something wrong etc. Being uncertaint is closely related to fear.

A few things helped me to get rid of it: realizing where the fear came from, raising my self-esteem, living life just as I want it, and doing exactly what I was afraid of.

You’re in a bad frame of mind. You need to change your thinking habits. Do not allow your mind to delve into those thoughts. Find a saying or something that you force yourself to focus on until the thoughts are gone.
