@Valentino , could healthy shame (rather than guilt), be predominantly intellectual (as in, I wish to live up to my standard or self-expectation, while forgiving myself when I don't), whereas toxic shame is emotional-based ('feeling' cringe-worthy, like one should hide or is rotten to the core, as it were), the 'feeling' without even explanation, even if one has specifics that one is ashamed of but the degree of shame is very large?
I think shame is a core primary emotion, it's the glue that holds the self, relationships and society together. It can be replaced with intellectual flavor of guilt. But then it loses it's fluidity, flexibility and integration. Intellect responds a lot slower than emotions, and also doesn't have the same energy behind it to get us to respond properly and fast enough.
I would say that healthy shame is just raw emotional shame that we in feel our body, as a communication from our body, that is then properly translated, understood and integrated by our mind and intellectual body.
Toxic shame is more about shame that binds with painful emotions, suffering, stories, unresolved grief, etc. There is often shame to feel shame. These complex layers of unresolved shame become a big mass of energy which can become like 'a pain body', that starts to have it's own identity, unconsciously acting out almost like a demon hiding within our shadow. ie. 'Skeleton in our closet'
In this state of being overwhelmed by toxic shame, it can be very easy to associate the emotion of shame as 'the' trigger that brings out our 'pain body'. Then the driving motivation for all behavior is to avoid feeling shame at all costs. It's easy to retreat to the mind and try to intellectualize strategies and stories to justify and rationalize these unhealthy strategies.
But, it is still an active strategy to almost intentionally dissociate. The mental body is fighting the emotional body, and there can be only one winner, but even if you win you still lose because you become fractured (dissociation) and your emotional body gets exhausted creating deep depression. Then life becomes a constant alternating battle between periods of fighting shame, and periods of fighting depression.
Sure, in the short term, coping strategies to avoid toxic shame can be extremely helpful. But for long term recovery and healing, there needs to come a point where we have to be willing to actively deal with our unresolved emotional wounds.
Sometimes the only way out is through. What you resist persists. What you turn away from, follows you.
