Have you heard of Compasionate Mind?

Compassionate Mind Foundation

Paul Gilbert is a psychologist who noticed that CBT has less impact for some people. He believes that this is because we haven't developed well the self soothing part of the mind, so while CBT gives intellectual reassurance, if this part of our mind is not working so well it's hard to feel the reassurance. The exercises are based on mindfulness, but are designed specifically to grow the soothing connections we didn't grow when young. They have functionalMRI scan evidence, that it is possible to develop these aspects, even as adults. You can download some of the exercises and theory free of charge I believe.

It's not a miracle, but just maybe....

Best of luck and warm hugs.
