Your comments mirror my experiences perfectly. I had several Christmas functions to attend and truly had a difficult time getting through it all because of us precisely the factors you describe.
And like you, I have a Super Bowl party on Sunday (with a bunch of college kids no less
-- that my son invited me to. Actually I know most of them very well and luv 'em to pieces.) As much fun as it will be in some ways, I am certainly dreading it in others.
That said, I have learned a lot in my few short months on this forum and about
myself and this syndrome, thanks to my medical providers and tons of internet research. I'm (finally) learning to "listen" to my body, so if it's too much I'll just head out and I know my son will understand. I just think it was very sweet of him to invite us.
GO PACK GO!
