Opposite of nesting?

I was always told you will get this burst of energy at the end of your pregnancy. Well I got the exact opposite of that! I am 39+1 I stopped working Sunday 38+5 and I don't even have the energy to change out of my pjs let alone shower cook or clean! I have so much laundry to put away and I cannot find the energy to do it at all! Wah! What are some ways to gain my energy back?!?!?!
