Easier said than done, but could you enjoy the fear? Become conscious that you’re creating the emotion —emotions are created by us, they don’t “fall” on us by circumstances. Notice that it serves a purpose. Contemplate fear instead of avoiding it. What is it? It’s an experience, like being bored. Or when you feel boredom. Separating the emotion from yourself in this way helps us realize that it’s not us. It’s external to you, like having blue hair — as much as you dislike it, it’s not really you.
Fear components:
Relative to the future: can’t experience it if you live in the present (not creating a possibility of a future)
Holding a concept of an experience you’re unwilling to go through (stop creating the concept or be willing to experience it)
The experience you’re unwilling to go through happening in the future
So practice, do it anyways, and contemplate it.
