You might want to consider looking on line for a sample will and draw one up, have someone witness your signing and dating it. I know I may be a bit of a Debbie downer on this, but it is important that you have something written down and give it to someone you trust. You never know what tomorrow will bring...not saying anything will happen, but you want to make sure that your children are taken care of and what you want them to have.
As for the meeting, I think you did just fine. You stood up for your children. You asked questions and pointed out things to everyone. I am hoping and praying that there will be some progress made in the days ahead.
Please take care of yourself.
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.
