These feelings are a part of who I am, and sometimes I have to acknowledge them a bit to understand why they are there, why they've always been there. They are very real to me. Despite that, they are not the controlling factor of everything. My friend gave me this great quote a while ago from an article by Terry Warner called "What We Are."
"One of our most dominant almost unexamined fictions is that we are not responsible for our emotions."
It is good to remember that the Spirit is not the same as emotion. Often extreme emotions can mask the Spirit. This is certainly the case with fear, anxiety, panic, and even excitement.
I'd like to share this great TED talk with you, in which Brene Brown talks about vulnerability as the heart of the connections we enjoy in life and shame as that which destroys those connections. She also gives a great definition of courage that I like very much.
