WR,
Yes, you can do this. You are strong and independent and your sons will enjoy their evening out w/their father and his sister's family.

I'm glad to see that your deliveries are completed and now you can finish up some other stuff and then relax.

Merry Christmas to you and your family.

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.
