Dismissing Thoughts That May Be True

I just watched the replay of Brooke’s last live coaching call. In the coaching about anxiety, Brooke speaks of waking up at night and her brain says “you shouldn’t have said that,” or “that was mean” (not quoting here). She then tells her brain “noted, but that’s not true.” I understand judging yourself does not serve you, but realizing you said/did something that was unkind should not be swept away. Was this just an oversimplified explanation? Should it be “right, that was unkind, I will clarify what I meant to convey in a more effective way with that person tomorrow” while also thanking your subconscious for the gentle nudge, and then forgiving yourself?
