Don't believe the bad stuff
Do you remember the scene in Pretty Woman where Julia Roberts (Vivian) is in bed with Richard Gere? Lying in bed, he tells her "you can be so much more". Vivian blinks softly and answers "the bad stuff is easier to believe." I still tear up hearing that line.
We all have those occasional negative voices in our heads; some just speak louder.
It takes practice, but we can learn to change the channel when we hear a damaging song in our heads. The frequency is our ability to face the fear and believe we are worthy.
It's a beautiful thing to realize - we don't have to believe the bad stuff.
