I am in the same boat also. My all-over body pain and insomnia started suddenly two years ago, five days after having Covid for the first time. It took a year to be diagnosed with fibromyalgia. I wonder if it could be a combination of the two. Both conditions have no cure, and people don't understand because there is no ultimate medical test to confirm either disease, so we get labeled "complainers" or "hypochondriacs". I find doctors not very understanding or helpful. I try to remind myself that some people have conditions much worse, yet everyday I miss my old life too..
