I can not seem to focus on work today.

I can not seem to focus on work today. I have a lot of reports to get through today, I have to do coaching with three of my agents today and listen to at least 9 calls today. I have been working for an hour and feel like I have not done anything except fix time sheets. I am running on like 3 hours of sleep. I want so bad just to close my laptop & climb into bed and sleep the day away until I pick the kids up from daycare but that is not an option. I have a meeting at 12:30 & I am in no way prepared for it.
