I had an 8 week dizzy spell in fall of 2020. Never had anything like it before, didn’t have any other symptoms. Went to ENT and ears were completely fine.

I have no idea if it was anxiety or Covid, but the dizziness was disorienting, at the worst I couldn’t walk , it felt like I was on a boat. During this time I had anxiety attacks almost non stop-triggered by the vertigo. As soon as I started to notice the vertigo I would begin to spiral because it was so unprecedented and disorienting. It just cleared up on its own after 8 weeks.

Part of the vertigo was dizzy spells every time I stood up.

I had ~ptsd from it for a full year, every time I stood up I would brace for the vertigo ,

Hope you find some relief soon
