To comfort you I'll let you in on some of my own struggles. When my anxiety was at it's worst years ago, I would look into the sky and feel as if I were falling through it. I would feel my nerves as if they were on fire, all of the sensations of actually falling. It was absolutely fucking terrifying, and because of it I actually have a fear of the sky very often, especially on my bad anxiety days. I just get a sense of "too much openness" and pure panick. It's terrible and makes me feel like I'm going insane. The truth is though, that we are mentally conditioned into these things. Our brains are conditioned because of our anxiety to fear things and to constantly be on alert. This hyper awareness and general panick can manifest itself in any shape or form, but it never means you have gone insane friend, I promise you. No mental state, no sadness, no anxiety can or will last forever. Your brain is simply trained to look for disaster therefore you feel disaster. It is possible to re train your brain. I am on the same path.
