I was diagnosed with GAD when I was 20 and never once had an anxiety attack that caused a form of blurry vision in my left eye til today. 

I started feeling an attack; I wasn’t hyperventilating but my breathing was off and I started feeling like I had vertigo. My left eye was blurry in certain parts causing me to feel dizzy. It took ten minutes to recover from the weird blurry vision, but I definitely felt like I was going to pass out. 

That… was an experience I never want ever again.
