The best explanation I have heard for shame is a simple acronym:
It’s the feeling that tells us to figure things out on our own. Don’t ask for help. Don’t admit weakness or needs. Keep the facade up, act like you know what the topic of conversation is about. Shame is a master at keeping secrets (where addictions come from). It will hold you in hiding until you feel like you’re enough. When you’re supposed to be a master of everything, there’s no grace or forgiveness for messing up anything.
On the flip side, shame tells us that we have limits, that we are not God. Which, if you can accept it, is a really freeing feeling. There is a God, and that is not me, which means I don’t have to have it all figured out. I can master some things, but only a mastery that a human can achieve, not the mastery of what God can achieve. Admitting this will lead to an ability to ask for help.
What do you need help with in your life?
