Child complains about not feeling loved during corrections

We are a few months in (our parent training was in January) and our strong-willed 9yo often complains during corrections that we don’t respect her and that we don’t care about how she feels and only want to control her. We do well with calmness but may need to improve on family nights and praises and councils, however, I’m honestly not sure if all the connecting in the world would prevent her from being highly offended during a correction. She wants to say her piece but will decide to drop the subject, but I think she is resentful inside that she has to use the TSG process, and it seems to be causing her to be increasingly frustrated when a correction begins, as if she sees the path unfolding and her options narrowing. She currently doesn’t seem to grasp the correlation between self government and self empowerment, and I’m not sure I explain it well. She is ADHD and impulsive and a very strong personality, and before TSG she got a lot of negative attention and saw a lot of exasperation from us, and sadly I believe it damaged her self image, so I think what happens is she lashes out to protect herself when we are correcting because she interprets it as we disapprove of her. Even when we are smiling and encouraging during the correction process, and even when I talk to her regularly about how wonderful she is, she still believes that she is hard and frustrating and often feels unloved. Do you have words of wisdom on how to gain the trust of a child who beats themselves up with shame but to your face is gearing up for a battle of the wills?
