I don't believe in shame.
Oh I hear you now- but "what about when I do something really terrible Krysta? I should feel badly for it."
Yes. Feeling conviction or remorse is a healthy sign of an intact conscience; but that's not shame.
Like hopelessness, shame seeks to have the last word. It's a period at the end of the sentence which intends to gobble up anything that comes after. Shame is sticky and heavy and weighs you down.
