I do this a lot, but mainly with regrets in my life which leads to temporary depression. I've done this basically all my life. In the minor form, telling people facts that I have not remembered correctly often leads to me calling myself a dumbass repeatedly in my head for hours, sometimes days. The major form of this often involves me thinking about missed opportunities in my life that could have greatly improved it. Relationships, education decisions, etc. I think it's because I have a bit of an inferiority complex and anything that reinforces that feeling of insecurity will make stress and depression set in again. Shit sucks.
