I was told it was anxiety when I was in the ER with serotonin syndrome....BP 300/240...
My antidepressant "cocktail" proved to be neurotoxic to me, and almost a year later, this was confirmed by a dysautonomia (autonomic neuropathy) specialist.

The turning point for me medically was my positive result for a SFN skin biopsy. Docs could not say it was anxiety. Yet it is all interconnected....we have only one brain. My slew of dysautonomia symptoms rode in on a wave of severe depression. I called around and got a great neurologist/psychiatrist who mediated my visits with the (doubting) testing neurologist, while ably counseling me. By the way, sensory neuropathy is just now kicking in for me....high gear.

I would suggest you go to the "Dysautonomia International" (DINET) ** information for doctors (and for yourself). With this in hand, try to find a sympathetic neurologist and get a SFN skin biopsy ASAP: this validates your symptoms. All of this can take months, so be prepared.

This is a tough road....hard to be taken seriously, and few treatments if you are. I do yoga and meditation...I also see a therapist. I was VERY ill with profound fatigue, but I am doing better each day....the depression is lifting. Although my neuropathic pain is increasing, many of my dysautonomic symptoms are improving. Yet I cannot work: this part is very hard for me. So, I suggest you get psychological support as you navigate this maze.

All my best,
