I did end up going into work.  I really debated either calling off or just not showing up.  I woke up with Z and ate bagels with her for breakfast, she was being so sweet and playing on her new leap pad, and it was snowy out and cold, but I sucked it up and went in.  It was totally fine as soon as I got there.  I love the women in my department.  I like interacting with other women, I like being treated respectfully and like a peer, not the baby sister or the youngest daughter, and not the main caretaker.  Just an average equal.
