Too much

I have NEVER EVER been this exhasted. I can only think about making it to the end of the day let alone this pregnancy. Why are two year olds so hard? She is so stubborn right now I feel like we are constantly fighting and I am constantly yelling at her. I have been so sick during this pregnancy. We are so cramped in this house and I cannot keep it clean. I feel like there is clutter EVERYWHERE. I am also worried that after I have this baby I will still be this exhasted. I so hope I don't get the baby blues. I have yet to get more than three good hours of sleep. ARRRRGGGH
