Thank you. Long Covid is exactly what prompted me to create this post. I've been having symptoms for 15 weeks (insomnia, brain fog, exhaustion). My primary care doctor was useless.

I've since discovered a lot of literature on my own that has validated my experience: that it's typical for general doctors to have no clue, they're still working on finding good biomarkers for the condition (it's not easy to test for), and I've learned a bunch about PEM (post-exertional malaise) and self-pacing / energy-management techniques to prevent the push-crash cycle that people with Long Covid experience.
