How do you deal with chronic fatigue, brain fog and burnout as a developer?

Hey everyone! I’ve been working as a software engineer for a few years, but lately my fatigue and brain fog are completely out of control. Even after a good sleep, I feel drained. I really want to check my biomarkers and see if it's a hormone or vitamin issue. Can anyone recommend a professional telehealth clinic in the US that specializes in deep blood work and wellness optimization?
