Hi Katie! So sorry you are dealing with this. I have had RSD for almost 22 1/2 years. I can relate to your cognitive issues 100%. My RSD has spread so much the last couple of years and with that, I noticed the "mind" problems. I am nothing like my former self. Just in the last week I picked up a hot pizza stone that I had just taken out of the oven, didn't even think about putting on an oven mitt. I put something in the toaster oven and forgot all about it, forgot to pay our cell phone bill (could've sworn I already did it). Husband doesn't want me using appliances when he is not home. I struggle with finding simple words to finish a sentence. I also have a hard time comprehending some of the simplest things.
The last day I worked was December 28, 2012. I was a financial & human resource manager. I was known for being so detailed and having a mind like a steel trap. I knew I was in trouble when I started making mistakes at work and forgetting to do time sensitive things.
This is so unlike me, and I have had a hard time with accepting it. While I am sorry that you are dealing with this too, I am glad to know I am not alone.
All the best,
Nanc
