Get your butt on the trail to recovery and fitness at that same time. And then, if you don't, don't sweat that either. It's easy to be hard on yourself during the holidays. But your own peace of mind, and your own acceptance of yourself, just as you are, is the most important thing you can learn this season.
Live your life as you would like to see your kids living theirs. Show them the adults they can be, by demonstrating the best that you can be. Anything less is a miss. Parenting and co-parenting resources come and go, theories of parenting and how do recover from divorce will change from season to season, but this truth never changes.
So much of co-parenting is about negotiation and compromise. We no longer have the same loving emotional ties to our former partners. We no longer have to make their urgency and priorities our own.
There will be time for anger. There will be moments when anger is the only way you can find to stand up for what you believe to be right. But the rest is up to you.
