One of my main physical symptoms of anxiety used to be nausea and I had intense fear of vomiting in public. 

I can’t pinpoint when it happened, but now my most bothersome physical symptom has become lightheadedness/blurry vision which now links to a fear of passing out in public. 

All of these symptoms suck, but at least with the nausea it was familiar. How do people deal with the blurry vision and lightheadedness?! And why does anxiety have to be so sneaky and change on us like this? Ugh.
