I understand your being hesitant. You've got to go with what you feel is best given your situation. However, she's going to feel and do whatever she feels and wants regardless of what you do.
Best of luck to you. I hope you have a great and positive day regardless of whether you are able to spend it with your kids or not.
I can't imagine the pain you have in being away from your children. Hang in there and be strong today.
