I also have severe Fibromyalgia...I don't have any of the items that you have listed. Don't have the extra money for them, since I had to quit working due to the Fibro.
All I can say is don't give in to it....keep doing as much as you can, every day...even on the bad days, do something...if you don't use it, you will lose it, according to my Dr.
I do have the Martelli rotary cutter, and I love it.....
