The uncertainty is awful. It took me ten years to get diagnosed with anything. I had so many doctors that thought I was just seeking pain pills. I had to beg a primary care physician to refer me to a rheumatologist. The rheumatologist guessed what I had within 5 minutes. A few blood tests, X-rays, and an MRI later and I had a diagnosis. Ten years and then someone guesses it in 5 minutes. Autoimmune diseases are weird like that.

I'm also incredibly pro-vax, but those things knock me on my ass for days. Seems pretty common for people with autoimmune diseases.
