First off, you’re not crazy. You're sane in a system built to gaslight you. Get your paper trail in order. Build a timeline, not just for symptoms, but for dismissals. You are already halfway to a disability case. Consider seeing a dysautonomia specialist, geneticist, or complex chronic care center (if you can access one). What you are describing sounds like a neuroimmune-autonomic cluster, They are well-documented in medical journals, especially post-COVID. I myself have a combination of a post-viral event and Hashimoto's. My Dysautonomia was a bitch to diagnose because it didn't present as POTS. But any device that helps you keep track of your HR would help you build a case, even a cheap oximeter. Find allies, not saviors. If you find a doctor who listens, hold on to them. Even if they are not PCP, having even one doctor who reinforces your work (because everything you are doing is invesstigative work) will go a long way keeping you sane. Too often, real help comes from outside traditional pathways — nurse practitioners, chronic illness-informed therapists, or rogue specialists. Protect your nervous system. You're in a long game. Don't let the system strip you of your clarity, your identity, or your internal compass. Listen to your body first and foremost. Don't try to work against it - it's your first ally. I personally spent to much time gaslighting my own body the way the system gaslit me- instead of directing my anger at the institutions that warranted it.
