I was researching the topic of feeling unworthy . . . and came upon these TED talks. I thought they might be helpful to someone here. I found them insightful:

Brené Brown: The power of vulnerability | Video on TED.com

Brené Brown: Listening to shame | Video on TED.com

Note that you can get a transcript just below the video image by clicking the dropdown arrow and picking a language. When you do that, the transcript shows up. You can read the transcript instead of watching the video if you like, which is a lot faster.
