I am a bit new here...and reading your post makes me cry... I am so sensitive to other people and their feelings.
I am so sorry this is going on with your husband... did he ever go to the doctor with your and have your illness explained to him and your limitations.
Stress does play a big factor with pain and other symptons of fibro....
I have this with members of my family and now I chose to not talk to them except when I really have to.....
Of course you cannot do that as your husband is in the house with you whereas my family is not....
My husband died in 2008 but he totally understood my fibro, vertigo and anxiety and said to me Sweetheart it is not your fault you are sick.
He never complained about me being sick and how I wish he were here now.. as I truly had a husband who was terrific.
I hope in time that you will be able to sit down with your husband and have him see that you could only do so much.. and IT IS NOT YOUR FAULT YOU ARE SICK AND IF YOU WERE NOT SICK YOU WOULD SURELY BE DOING ALL YOU COULD DO...LIKE "NORMAL PEOPLE"
again I am sorry this is happening ........
gentle hugs.
