Treese, You are not alone, there are many in the same situation who are struggling this time of year especially. Here is a suggestion for your son if he wants to give gifts. Tell him that the giving of himself is enough. If he really wants to give something, maybe do a little card with chores that he will volunteer to do throughout the year for you and the family. It's a gift from the heart. It's the "old" fashion Christmas type of things and not gifts that have monetary value placed upon them.
The Christmas in the Courtyard sounds very nice and I'm sure the children will enjoy it. There are so many children out in the world that do not have the privilege of receiving gifts on Christmas. This is truly giving from the heart and I do hope it is a success!
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.
