c, I am so sorry to hear of your uncle passing and now your SIL. Please accept my condolences.
You've got a lot on your plate and it's very understandable why you are feeling down. My goodness, you've had two losses in less than a week and your son won't be w/you on his birthday.
Why not set a day aside and make that day his special birthday w/you? Do something fun and just enjoy the time you spend w/him on that special day. I'm sure he would enjoy himself and you know what? He'll be happy to be w/his mother doing something extra special.
Please take care of yourself during this time of sorrow. Stress has a way of kicking the immune system in the gut when we are stressed.
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.
