If they resist feeling good maybe its that "good" has no definition or meaning in their worlds and context- like they simply cannot relate to a word/concept that is so very foriegn and out of their realm of existence.

Is it a possibility to go to a dictionary and thesourus and define in concrete terms and pictures exactly what "good" means when related to feeling and being- to see if they can start to wrap their minds around this language?

I've had to keep a dictionary handy for this purpose and here and now is the ONLY time I've ever shared that with anyone in my life. Will you try it?
