I understand completely AMN!

And you have a way with words, for example: At the get-together when DH wanted to leave early, right after lunch

you looked at him and jokingly said, 'Don't be a piece of dry toast!' You
could have said, 'Why do you want to ruin all the fun by leaving early, you party-pooper?'
But again, I know where you're coming from. If you can do something better for yourself and save energy doing so, then ok. People should understand.
Sometimes after a relapse, people won't let me lift anything but I have to insist that if I don't do
some physical things, it isn't doing me any good. If I feel that I
can't do it, I
will ask for help! Or if I can't participate in something, I'll be sure to say so. I generally know my limitations.
