Yes, in fact I was DXd with CFS 30+ years ago. Not "recovered" yet. Unable to work.
Now that I have looked into autism, youtube, reading, taking tests, I am significantly autistic. I am thinking that CFS was/is the wrong DX.
I hope that getting a "real DX" could help me with services, therapy, etc.
In CFS community there are traits that are autistic anxiety, exhaustion with social interaction, hypersensitivity (light sounds smell etc.) unable to get or keep a job (without large defecits in other aspects of living) etc. CFS majority are females. Doesnt that sound especially for females, undiagnosed autistic? Very tiny I think 5 % as per the NIH fully recover. It becomes lifelong, but maybe it is lifelong born autistic that reached and stayed in breakdown mode, from keep trying keep trying keep trying...
I do get the flu like symptoms, glands swell/tender, malaise, sore muscles.
I hope this was of some use.
