I do understand. Use that anger in a productive way, i.e., to get things done that you've been putting off or go pound a pillow. Whatever you do, don't show that side to him. You want to show him that you are calm, level headed and businesslike. That will back him up just a bit and he'll wonder what happened to the old Heather that would be quaking in her boots.

I'm very sorry this fell into your lap at Thanksgiving, but it's typical of the MLCer. I'm not making excuses because it could have waited until Friday or even Monday.

Please take care of yourself. Okay?

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
