Shame is a painful feeling that’s a mix of regret, dishonor, and self-hate…. When you feel shame, you feel like a bad person. Shame can leave us feeling like there is something inherently wrong with us. It can leave us feeling like a failure, worthless, and unlovable. Shame also leads us to believe that we can never recover from our mistakes. In fact, we might feel like we are the mistake! Shame leaves us feeling flawed and unworthy of love and belonging. One way to combat shame is to understand what it is, and how it presents in our lives.
