I get it Frankie! I can be critical that I am self-critical! Wow!!
It may be hugely helpful --it is for me-- to connect this powerful inner critic activity to symptoms/TMS. That is, you have great evidence of Tension down deep. Knowing this, and connecting this as the cause of symptoms can go a long way, even without having to "fix" anything psychologically. Next time you notice a symptom, you can simply acknowledge: Oh, this is a manifestation of my inner tension. I get this!
