What helped me was to take a photo of myself as a child beforehand, reassuring little Sorina that she's safe, loved, and enough as she is and that I will always love and protect her no matter what. Maybe it will also help Maria.
Yes, I agree, it's tricky with the feedback part, I try to lower resistance as much as I can and filter it through my awareness whenever I feel myself getting defensive. In the end, I want to leave room for improvement but still keep my essence and authenticity. Also, I have to make peace that I am not for everyone and that some might not like me and that's perfectly fine.
