I like Bradshaw, I saw a number of his talks when I was in rehab.

One of the things that helped me move past shame was asking myself what I got out of holding onto it, and that helped me to realize that there was absolutely no value add to continuing to feel shame and so I was gradually able to move past it, as every time I started to feel shame, I was able to do self talk to stop the thought.

The other thing I find helpful is the practice of mindfulness and its focus on staying in the present. I use its precepts to get out of negative emotions in general as generally none of them are valid in the here and now.

But the biggest game changer for me in moving past shame was getting and staying sober. I used to have a lot of shame associated with my pattern of repeated relapses, but I've been sober now for almost 4.5 years and I know it's extremely unlikely that I'd go back to drinking now. That eliminated a lot of my sources of shame.
