I feel you pain. I have been trying to work on a quilt for DH and I... I'm really excited about it, but I have pushed myself too far at the cutting mat (takes it out of me the most, it seems). I have fibro too (diagnosed in HS)... I am sitting at the computer with ice on my back as I type. I hope you get to feeling better! Rest up! I know if I get in a hurry or push myself too hard I end up sick and making stupid mistakes which are even more frustrating and time consuming.
