Try adaptive pacing instead of GET, you’ll get much better results. Read Tom Kindlon, et al’s work on debunking GET. I can provide links, to papers etc if anyone wants them.

Side note: I have had ME/CFS since 2003, (partially bed bound and mostly housebound, raising 3 kids with my wife who now is also diagnosed) when it knocked me out of my USAF Reservist and my systems engineering careers. I helped admin PhoenixRising.me (a charity & forums for ME/CFS patients and allies) for many years.

If anyone has any questions about ME/CFS (aka SEIDs) or coping with it, feel free to ask.

Edit: Please follow and read some Jen Brea’s work on twitter: https://twitter.com/jenbrea/ and please try to watch (Sundance award winning!) “unrest” by @jenbrea .
