Patiently waiting for baby

HA! Give me a break, that was easy to say 3 months ago. Now, not so much. I think patience flies out the window once you pass your due date and are still pregnant. I am DONE! I am miserable and uncomfortable and just flat out done being pregnant. I have baked my little one for well over 40 weeks and endured the aches, discomforts and emotional strain to go along with it. I can't help but to think, what is wrong with me? Is there something wrong with my body or my baby that is preventing me from going into labor or her from being born yet? Will I be one of those women who goes well over a week overdue - or....MORE! Ahhh! I'd like to keep faith in my body and trust that it will do what it needs to and go into labor when we're both ready. I have seen women go 10-14 or even more days over and it makes me wonder, why? Or is it just a misconception that all babies should be born by now, like the 37 week "full term"?
Either way, I'm miserable and very ready for this pregnancy to be over with! 40 weeks and 2 days is plenty for me, and I know I am doing everything possible to give this baby the best start. So why me? Why am I one of the unlucky ones?
I'm starting to think that I need to just disconnect myself from everyone completely for a few days. It's doing well to keep my spirits up, but I don't even want to think about being pregnant anymore or even about the baby for that matter. I know that sounds horrible, but I have definitely felt more disconnected from this pregnancy than I was with the last one. I think much of it is just this being the second baby and learning to split my love and attention. I know once she is born, that will all change. It's just so hard to walk into her room or see her things and be constantly reminded that she should be using these things. I walked into her room yesterday to put a new outfit away and couldn't even let myself think about her at that point. I just felt so depressed looking at all of the baby items in her closet, waiting to be used. Is it better this way? I don't know, I'm starting to wonder if I should get myself more involved in this pregnancy and get psyched up for labor and birth again. I don't want to watch A Baby Story or birth videos online. I want to be inspired, to get myself excited about this birth, but I hate the constant reminder of not having that yet. I know that once this baby is here, in the grand scheme of things, this will be nothing. I will forget all about the way I have felt these past few days and weeks. The problem is, how to get through it? How do I get through each day and deal with the different emotions I'm going through? The anticipation of what is to come is the worst, not knowing when it will happen or if it could be a day or a week.
