In order to resolve shame, you need to have an ongoing reparative relationship with another person who will help you challenge your internal voice of shame and replace it with a healthier dialogue. Your therapist is an important ally in helping you to transform the shame into self-acceptance. Talk about your shame with him/her and share how you experience shame in your life, including in your therapy sessions.
With your therapist's help, identify the ways in which you keep yourself from feeling your shame by adopting a role or "false self" that you portray to others. Share this "false self" with your therapist and try to understand what the role gives you that you feel you lack inside.
