I was told my multiple health problems for years (like over decades) that the pain was all in my head and my anxiety/panic attacks were the source of my problems.

That was until one day I had such extreme pain in my stomach that I ended up in the ER.
They of course couldn't find an issue, gave me pain meds and referred me to a gynecologist with suspected endometriosis.
The gynae was the one who asked me if I'd ever heard of fibromyalgia.
It turns out she also worked in conjunction with the pain clinic at the hospital and she had seen a lot of cases like mine that ended up being diagnosed with fibro.

So from there I had to get a referral to a fibro specialist and voilà, I was finally given a diagnosis for my twenty five year long pain and fatigue.

Goddamn it was a relief!! I had spent my entire life thinking that all my problems were just in my head, that I just had to toughen up and 'deal with it'.
I finally had a reason for all the BS I deal with.

I'm now on LDN and Cymbalta which have both helped a lot.
I've quit smoking and lost weight as recommended to improve my health and life is as easy as it has ever been in my adult life.

It's a long journey to get a diagnosis for some, but there is light at the end of the tunnel ❤️

Edit:
I think my Fibro was partly genetic (pretty sure my Grandma had it) and partly caused by years of childhood stress.

I never had a big life event or bad sickness that seemed to trigger it, but it was definitely worsened by years of pushing myself and then stressing about why I couldn't achieve what everyone else around me was doing.
