Not touching the ground
Being outside your comfort zone could also have something to do with the ideas you are exploring. Being willing to follow a thought or a feeling to see where it leads you. That can be daunting, because not all emotions or ideas are easy to explore, and it can lead to some highly personal works. Art can be a way of healing, but to get there, you have to expose your wounds, the cracks in your story, and this can feel like a jump into the void.
