agoraphobia
i had mild agoraphobia before my SFN got bad, and then once my pain started spiralling out of control, i started locking myself inside and drawing the curtains and not speaking to anyone for weeks. at one point, i hadn't left my apartment complex at all in 2 months.
has anyone else developed agoraphobia or something like that because of your symptoms and pain? like an overwhelming fear of any situation you can't control, wanting to isolate yourself, feeling unusually exhausted after any social interaction, etc
