Jen Brea is a person with ME/CFS who made the amazing documentary Unrest. It’s interesting that her health has seen huge swings over time- it’s another piece of evidence that recovery is possible.
Here she is talking about how her POTS is in remission:

And later on she talks about how her health improved to the point where she could do advocacy work full-time. “My ME is in remission”

Unfortunately a few years later her health worsened and she had to step down again.
