You sound so strong in your posting. I'm glad you are doing well and I hope that the discussion w/the children comes off okay. I agree, if you keep things on a positive note, they will be okay. They'll have some concerns, but I believe you can handle those quite well.
The new year has started off on the right foot for you. You have found your footing and know what you need to do for you and for your children.
Stay positive!
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.
