Sounds like you had a busy day. Hopefully you will find some time to take care of you. Get your bloodwork completed so that you don't have to worry about it later. Your health is the most important thing that you need to take care of right now.
As for the children, they'll return before you know it w/plenty to tell you of their adventures w/dad.
Take care.
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.
