I am so sorry, my friend. That brain fog can really make a person feel stupid as hell. I would rather deal with the pain most of the time than the derps from the fibro/cfs. I used to be so on the ball! Now? Yep, just like you, I don't know my own name sometimes.

And not that you asked for my opinion, but I really think you should go for the short term disability. The stress of wondering if you can make it through a day of work probably isn't helping you :(

Hang in there <3
