Hitting The Wall

How can a day be both so up and so down?
Today was a great day on the blog. I felt I was making some headway and starting to work on improving my life. Hell I even busted out a new dance move.
But that was then and this is now...
I'm about to have a complete break down. I feel depressed and overwhelmed and disappointed. I realize much of this is due to my serious state of sleep deprivation. Baby has been up (literally... and when I say that I mean that) a minimum of 10 times every night for 2.5 weeks. I just can't do it anymore and I want to fall on the floor in a fit of sobs. Her top teeth are finally breaking through (she has only had her two bottom teeth for the last 5 months) and I'm hoping that this bad phase will end. But apparently not tonight. Right now I'm exhausted and it is all I can do to contain my strong desire to start screaming and slamming doors and walking off. If I had anywhere to go... believe me I would go... right now.
I'm done. It is too much. I need a break.
