Mona, You've accomplished quite a bit this week from working, to school work, being a mother and now a handy person to fixing things for your mother. Try to carve out a bit of time for yourself or you are going to burn yourself out.
I think your conversation w/your daughter was very good. I hope and pray that your h finds his way and reconnections w/his children and be the father they need...but it will take some time and a whole lot of patience.
Keep up the good work!
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.
