Just that. I'm exhausted. DD(2) isn't sleeping well and I've been working 80 hour weeks with one day off most weeks. Sometimes I have 13 days straight before a day off. I was at work 8-5 today and now I've got a work do this evening I have to go back for. How do I summon up the energy to get through tonight? (And then to get up and back in for 8 again in the morning!)
