I do the same ... for me it comes from several filters that I see the world through...

Unrelenting standards…nothing good enough…strive to meet excessively high standards to avoid criticism ... this is aimed at myself...some people aim it at others...

The other big filter for me is...

Defectiveness/Social Undesirability…belief that you are flawed, bad, socially inept or inferior. Hyper sensitive to criticism, rejection, and blame…insecure around others.

I've been in a class that seems to give me a bit more awareness and certainly a language I never had before.

These two "Filters" gets me everytime...though I have been challenging my thinking specifically when I look at these two filters when I start to think the same thoughts as you...
