I have been diagnosed with GAD and used to experience panic attacks. This really feels like a panic attack that is ongoing. It doesn’t feel like general anxiety but it doesn’t get my heart going like a panic attack. But in my head it feels exactly like a panic attack. It’s completely overwhelming and intense. I’m not really sure how to describe it. It just never ended. It was hellish. I don’t experience it in the slightest anymore with NAG.
