Back when I was a medical cannabis patient and convinced I had neuropathy (spoiler alert: it was TMS!), I came across an extreme version of this at my former dispensary.
She enthusiastically approached me after overhearing that my cannabis license was new. An overview of her fibromyalgia and "fibro warrior journey" made it clear that the diagnosis had consumed her entire life, to the point that she was only 27 and had already dashed any and all hopes of having job, romantic or physical relationships, travel experiences, etc. ever again. She was on disability and admitted to spending most of her time talking to "fibro warriors" online because her family and friends could not understand her reality or provide the support she needed. Her cushioned sandals were even custom made for her symptoms. I was handed a business card which contained some contact details and the URL to her fibro blog. She said we should become BFFL and meet up to enjoy cannabis brownies and trade joint pain stories. I remember thinking that she was charismatic, intelligent (but very misguided), and gorgeous. Her life absolutely could've been so much more than what it was. I immediately thought to myself, "I cannot let this happen to me."
I did not reach out to her and I'm very glad I never went down that path. I hope she can one day see her fibro for what it really is: a valid expression of the mind-body response that does indeed result in real symptoms but can be overcome. I think about her from time to time and always feel a bit sad.
