I don't have any ideas that would be new. I ran. A lot. I coached soccer too. The busier the better, especially if it involved friends. I tended to isolate myself, but always felt better when I didn't.
Do you and your W have a group of mutual friends around? Someting about that seems to help, especially to take some of the stress out of parenting.
On a side note - I've been gone a while - I'm really glad things are moving in a good direction.
