Drunken parents left me to be molested regularly when I was 7. I left the house full of drunken screaming and fighting to willingly be with my molester. I felt loved and wanted....
But I will take the side that shame can at times be positive.
If we are ashamed of some behavior of ours for legitimate reason, shame is the internal mechanism to change. If shame does not motivate us to change, then pain can. We may even get in legal trouble, in jail.
So looking T the root of our shame, and our part in it key. False shame and guilt, like feeling we asked for our CSA.... Bad. Living in violation of our own code of morals, then that is probably good shame.
Just my take on it.
I feel more like I do now than I did when I got here.
