Welcome to the Family, Ancestry!
Wow, just love that 'My way or the highway' attitude. NOT! I'm so glad you stood up for yourself. You shouldn't be down, YOU should be proud of yourself.
Sometimes, the ppl who are in charge of these programs do not have a clue as to what we can do or how long we can do something. I believe we should keep moving as best we can. That means walk, stretch, exercise at our level, not someone else's idea of how long we must maintain a level.
Who referred you to this course? Was it the dr or ins? I'm not crazy about this place not answering your questions. You are paying for this service, but even more importantly, it's your body. I'm so sorry you are having such pain.
I can't maintain any position for more than 10 minutes, sometimes that is an eternity.
Sherrine already directed you to 'Fibro 101', pls give it a look over. I think most of us go back to it quite often. Lots of good info and ideas that we can tailor to our abilities and limits.
I hope your day improves greatly.
God bless. Alice.
