Consider “Daring Greatly” by Brene Brown. She has a TED talk “The Power of Vulnerability” that you may also enjoy. She does a wonderful job of exposing the feeling of isolation, what drives it, and what to do about it.
Also, “Turning the Mind into an Ally” by Sakyong Mipham may resonate with you. What’s around you? What are you seeing? How are you relating to what you’re seeing? Holding yourself back? Etc. Are you your best friend and advocate? Is your mind gentle to yourself? Patient?
Namaste, happy seeking!
