So sorry your having such a bad day Hun... It's bad enough trying to cope with this condition, without having to worry about those around you understanding or not... I don't know what to say to you, other than sitting your Husband down and having a long chat about your condition, how it's effecting you, and long term, things will have to change, tell him you need support not dirty looks and making you feel inadequate.
I know where you are right now, I got divorced due to the lack of support, four years later I married a wonderful man, who loves me for who I am, and nothing is to much trouble... I am spiritual, and I have faith, but I am the one that has to live this life, and I am the one that needs to make choices to make my life all it can be, sometimes that means back tracking, or huge change, and yes it's twice as devistating because of the fibro and CFS ...I also suffer with both... My Mum passed away last year, I lost my Dad 11 years before that... I have no children,,just the love of my Husband to keep me warm... But it's a bed I made, a place I want to be, a place I can live more or less stress free, and that is so very important...
If your relationship is not working, and you have tried to make it work, best to walk away...as for your Mum, all very well telling you to give this condition to God, but that's not very helpful, sound like she would benafit from some research, or going to her doctors to find out more about your condition, in the vain hope it will help her understand... I am so sorry your having to live with this attitude around you, from the two people that should be your number one support... I really do wish you well...good luck x
