With more than 200 possible symptoms, long Covid isn’t easy to treat and diagnose. Rolled-back federal funding has led longhaulers to ask: is this all in my head?

I am 30ft below the surface of the Blue Grotto, a crystalline diving hole in central Florida. Between the water’s embrace and the restriction of my wetsuit, my blood pressure finally stabilizes. The long, deep breaths I pull from my respirator keep my heart rate nice and low.

I feel lighter than I have since April 2022, when I first contracted long Covid. I feel childlike at the fact that I can do this at all – get scuba certified – when on land I’m often confined to a wheelchair or a walker.
