I'm going to follow on T2's coat tail and wish you a happy birthday as well. The first year is always the worse. Some of them can be as nasty as h@ll. He's all bent out of shape because someone called him on his behavior and he couldn't go out and do whatever it is he wanted to do. Let him sit in a corner and stew.
I'm very glad you didn't have any expectations, but it still hurts no matter what. I do hope that you've got some great plans for today and can get out and enjoy the season. Don't worry about the baby...he'll straighten up a bit when he notices that no one is there to pat him on the back and tell him it will be all better.
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.
