I have some kind of depressive episodes when I first wake up. My daughter being in Boston is making me sick. I can't stand that whole effete Boston ethos.
One of the hardest things as a parent is letting go and allowing our children to find their own paths. I've done it 4 times.
I can imagine that you miss her. You must be very proud of her - I personally love Boston.
I've taken to hiking more - fresh air is always good for what ails you.
