GOTTA START SOMEWHERE

I don't even know where to begin... Do I begin with the pregnancy of my 1st born? And work my way up to the tragedy? Do I begin with the day my world collapsed? Do, I gripe about my current situation and just fill in the blanks as I feel them and the emotions come to me?

How do I break this down??? Should I create different blog sections to pertain to each situation so that things stay organized???
