Try affirmations at least times a day such as;
I love me.
My love is safe.
God is love
I am one with God
Or ask a question throughout the day such as How can I allow God to live through me? to replace the nagging negative thoughts or comments and questions. Maybe identify the problem and ask yourself "Can I let it go?" "Will I let it go?" "When is a good time to let it go?" "How about now?" a little Sedona for ya
