I very much used to be someone who would analyse everything (and overthink a lot), especially if it was someone I was having trouble with, or if it was a difficult situation I was in. I liked having all the loose threads tied up neatly, and felt that I had to before I could move on.

I was exactly the same. I hated conflict. I could analyze for days, and honestly, in hindsight, the analysis didn't make much difference; it just provided more time to stew.
Now, I say what's on my mind and move on. Life is better because of my change in attitude. It's a wonderful gift my XW gave me.
