I feel you are a former Fearful-avoidant leaning secure sweet person and would love to know whether my intuition is correct!
I'm way too familiar with the "Savior" pattern you're describing brilliantly here, my soul friend! It was triggered in the most horrific ways in May 2020.
I destroyed the 4 levels related to people that I was able to identify and I'm still dealing with the 5th level linked to the magical beings we call animals!
The progress has been too slow and I suspect the reason could be: unlike humans who can be independent and responsible, cats and dogs specifically — our ancestors creation — fully depend on our caregiving.
The savior pattern is merely one of the numerous coping mechanisms I had to create while raised in a dysfunctional, subtly manipulative and abusive family system. Its root cause is what we call "parentification"
