First of all, this article was so well written using the examples, it made it possible for me to read to the end ... because I saw myself in there and it was triggering.
Coming from a dysfunctional and abusive home, my sense of self was seriously fragmented and I was not able to stand any form of criticism. Owning up to even a small mistake meant that my mother was right and I was the unnecessary burden wasting the oxygen ..., and so I never did. I was always (painfully) right and in control, making up excuses or blaming someone else instead of apologizing and finding out how to clean up any mess I happened to make. It took years of healing and growth to understand that making mistakes was OK and I did not have to be the embodiment of perfection to deserve to breath the air.
Owning my mistakes became a concrete demonstration of compassion and unconditional love for myself.
