I am having a new thought that is causing me constant panic. But I am going to explain something first which is that breathing is a natural part of life and we are unaware of it.

But I asked myself the question of "what if I become aware of it?" Me being aware that I am constantly breathing is causing me panic because I realize that I have to put effort into every breath I make and that I can't escape. I feel trapped inside a body that has to constantly breathe in order to stay alive.

Since I am aware that I am breathing, I feel myself always having to choose (put effort) into breathing and this is what is causing me panic.
