Just needed to sook

I have no clue how I'm going to handle a new born. This whole pregnancy I have been living off of 2-4 hours of broken sleep a night. I'm wrecked. I have less than a week left and I'm feeling it. No matter how much I try sleep I can't and there is always something waking me up. An ant could sneeze and I would wake up. I'm on the verge of a melt down ):
