Oh Minny, it must be the weather as I think we all are feeling the same, Its rotten as when we have a good day we are all guilty of doing loads then suffering the next day, we need to pace ourselves, but its not easy, I have loads of sympathy for you as you are a single parent too, does you son know about Fibro? Mine have left home now but I made sure all my lot knew about Fibro, it gives them a better understanding of what you are going through, so when I'm having a bad day they know why, I think I am very lucky with my family, I know of peeps who's family dont care, cheer up lovey.
What goes round comes round, its a shame you cant be a fly on the wall to watch it happen.
