I am very sorry about your co-worker/friend. Unfortunately, her fall and hitting her head may have been the cause of her death. This is so very sad. I think Natasha Richardson may have had the same thing to her back in 2009.
I'm glad you got out of the house last evening even though it was a work function. Sounds like you had a good time.
Enjoy the rest of the weekend w/your son and fur babies.
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.
