Aw Alex. I hope she feels much better soon.
Re growing up, I agree it's gradual. University is a soft, gradual leaving really.
We've just been away without DC1 (now finished degree and working) to a place we went many times when kids were small. I really missed DC1. I dreamt she was on the beach with us aged 7 or 8 with her hair in a ponytail.
I don't want to be a middle aged menopausal woman missing us all being younger
.
Then I saw some grandparents helping with the big carry of stuff to the beach (bags, buggy, toddlers) and I thought this is our chance to do long walks along the cliffs, nice lunch etc and chance for DH and I to spend more time together.
Im also going to do an art class and an exercise class. I think it's ok to feel sentimental but I need to be where we are at now too.
