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 3.5 years 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.
