@EzzieD Your experience sounds a lot like mine.
I'm in Canada and became ill in 1991 from a sudden viral onset and several vaccinations soon after. After 9 months (without treatment) I recovered 90% and was able to return to work, but only to become disabled one month later.
My GP sent me to several specialists for all sorts of testing. I was taken seriously back then. There was only one doctor, an internist, who told me that he studied "CFS" for 10 years but no longer believed that the illness lasts for decades. I thought, "ok, that makes sense". What did I know? The weird thing back then was that I down played my illness and figured I would eventually recover.
Fatigue, tiredness, stressed etc were never mentioned or written on my medical reports- never once.
I was fortunate to see an M.E doctor in 1992 who helped me get disability. I was diagnosed with "atypical M.E", my diagnosis was sent to my GP and she believed I was disabled. Never once was it suggested that my illness was psychological.
I slowly improved for the next 6-7 years without treatment, and like you, had a terrible relapse in 2000. This is when the autonomic symptoms began and now I'm even more disabled.
In 2001 a Virologist ran some immune and DNA/RNA tests for viruses, my CD4,CD8 etc were all below normal range but nothing else was abnormal. He recommended CBT. I'd never heard of it so went online to read about it. Yikes, now they're telling me I fit (bio)psychosocial model or need to learn how to cope? They knew nothing about what I went through. I was stunned.
Fast forward to present, my GP asks how my 'chronic fatigue' is doing when I come in for my yearly physical. Yes, the same GP who took me seriously in 1991 now seems to think I'm 'fatigued'. I'm totally disabled!
Anyways, that's the short version of my experience
We have gone backwards in Canada and I totally agree with you on Bizarro World.
