Struggling to Focus at Work

Is anyone else finding themselves struggling at work lately? I feel so distracted and not as "into" what I do anymore. It's like getting pregnant helped me gain some perspective on what is truly important, except I feel like I'm struggling to stay focused now at work. It doesn't help that neither of my bosses (both female) have kids so neither one understands that the changes I have going through are not just physical, it's mental and emotional too. Am I alone in feeling like this?
