Oh I love when the body decides your under stress.. Mine does this.. IBS and migraines! Lovely stuff.. You have my empathy!
I'd just tell her that yes it is really hard work trying to get the balance right.. What would she suggest? ( I.e all help welcome).. Should go down better than going grrrrr( which is probably what you want to do.. I know I would).
Regarding stress levels.. I can only tell you how I cope ( I also run a business from home, have ds2.. And tw NT dc's with their own issues And a dh who although mostly fine isn't in the best of health... Rather dodgey liver and always in for tests etc).
( at this point I am wondering how I do cope.. )
basically I run the business around the dc's... So when they are at school, at my mums ( thanks mum).. And when they are in bed.
If I get the time I run.. Even if it's just 20 mins..
( obviously with me that would be a bit hard.. But the point is I do something just for me with noone around)
I make sure I do something daft everyday.. Even if it's racing with a trolley in sainsburys!
But mostly I try and section my life.. So it doesn't all get too much in one go.
Hth a little bit
