Summary
By June 2025, Harbor 61755, a 29-year-old woman, had been ill since June 2022 after an April 2022 COVID infection. She said symptoms were especially bad in June 2023, when she was doing spin classes and started Krav Maga, and thought excessive exertion set it off; she described one crash after restarting exercise and feared exercising. Vitamin B12 helped immediately and NYT games helped her brain fog; a one-time iron infusion brought iron levels back to normal. In March 2025 she said she felt exhausted, and in June 2025 that she walked her dogs three times a day.

Their path
How ill they were on the ME/CFS severity scale, estimated from what they describe at each point, with time counted from when the illness began. Hover or tap a point. The chart starts 12 months after onset: the story doesn’t say how ill they were before that. 1 step says too little to place on the scale and is only in the table. Dates are when they posted. What the levels mean.
