Hi...if you check out some of the posts in the anxiety forum, you'll find that pretty much everyone experiences symptoms of these differently. For example, I have both anxiety and panic, but neither causes me to see colors or feel like I'm going to pass out, as you've described. I have much different, yet just as serious, symptoms. Living alone, I don't blame you for calling 911. But that could get expensive fast. Maybe it's time to get a physical with blood work to rule out other things, especially if you were feeling dizzy. Have you been eating and hydrating well? Taking your meds? Getting some exercise to relieve stress and anxiety? Self care really has helped me. I hope that you can find the answer.
