Here is something to consider, though: shame (closely related to guilt and regret) is an essential part of our survival and functioning and, in fact, is a gift from Mother Nature.
Let’s back up here a bit and first talk about the functions of emotions generally. Emotions are hardwired into our brains and help to warn us, facilitate connections to other people, and work through challenges. “Positive” emotions such as joy, pride, and love tend to feel good, while “negative” emotions such as anger, shame, and sadness tend to cause discomfort. It is easy to want to push away and avoid the “negative” emotions, but it is important to note that both types of emotions are necessary in order to function in the healthiest way possible.
Now let’s get back to our friend, shame. Shame’s function is pretty important. Basically, it helps to keep us in check. Shame is a signal that there has been some sort of action that could harm others or ourselves. This could be an action that hurts a relationship with a loved one, something that could get us in trouble somehow, or a behavior that would be dangerous or harmful to us.
