I have recently been experiencing an extreme sensation of anxiety (more specifically, feelings of imbalance, light headed ness, heart racing, straight up fear, etc.) when in open spaces. The first time I experienced it was a few years ago in the Grand Canyon (first time visiting it) and brushed it off. I began to feel it more at the beach though and in a soccer field, until a recent trip to the Utah desert gave me a panic attack that had me literally running full speed back to the car to feel as though I was under a shelter of some sort. Ever since then, it has been more prevalent and I am experiencing unease or full on anxiety during walks, drives, or pretty much anytime I have to go outdoors. The sensation is also coupled with mental anxiety, such as existential thoughts, intrusive thoughts that I will “float” into the sky, awareness of the world, existence in general, etc. I should add that my biggest fear is death though and outer space is incredible but the thought of it makes me uneasy as well. Not sure if that’s relevant to it all. 

I’ve had my go around with anxiety before and have never previously struggled with leaving the house. I overcame my panic disorder a couple years ago actually and am not new to anxiety but in all honesty, I haven’t been this uncomfortable and anxious since my first bad panic attack a few years ago. Is this agoraphobia? Does anyone relate or has anyone worked through it? 

TLDR: feelings of panic/anxiety in open spaces (fields, deserts, highways, etc), coupled with existential thoughts and fears
