Rich, SadHub is right. Don't overthink things. Ride the waves as they come. Your D will be fine, it's really up to you how your D perceives things. My S11 adjusted quickly and he is fine, although he is still sad that mommy isn't there to do things with us as she has been for almost every activity for the past 11 years. But he understands that it's instigated by WW and not me. I'm fighting the sadness and resentment just like you, they cycle through constantly. The relief comes when I focus on other things like work or my son's games, they bring me great joy to see my S11 happy running around on the field. I mark my calendar with his schedule to focus happy thoughts around him. Find something like that for yourself to get through the tough period.
