I have similar tendencies. What changed for me was using journaling to understand and cope with my emotions during a very difficult time in life. By writing out my thoughts they were more complete and I could better asses them so it helped calm racing thoughts and patterns of rumination.

Ive come to enjoy the process materializing my thoughts into something concrete, as a thought isn't really fully formed until you write, speak, or type ot. I continue the practice as part of my morning routine and when I read at night.

I don't review what I've written or share it or have any plans to make a blog or something. I just use journaling to enjoyably process my thoughts.
