Thesis Status

I am tired.... Motherhood has completely wore me out. I think I sleep twice as much as I used to(and that was a lot!) I am tired of thinking about my thesis and pretending that I am working on it all the time. I am ready to be done. But I am so tired...and it isn't completely the sleepy tired-- it is the I can't think straight tired--the it takes me hours to remember what I was doing tired -- the brains flowing out of my head tired -- the can't make a cognitive sentence tired... I need HELP any suggestions? How do people get their brains back after childbirth?
