Get Ahold of Yourself Woman!

I am riddled with guilt over the events of the past 3 days. I have totally overwhelmed my kids with all of this change and I feel like now they are suddenly little nightmares.
I not very familiar with guilt. I talk about it alot but don't usually feel it. Mostly I am arrogant and feel I am right about most things thus guilt doesn't really apply. This, I honestly feel. It's exceptionally yucky.
I tried crying all morning but that didn't work.
My daughter has suddenly starting saying things like "get away from me!" and "I want daddy to come home - not YOU!"
I am such a baby, this really hurts me. I know I will get over it but I just see it as the first step in their true independance and it scares me. I like the happy cocoon we live in.
Can you imagine me leaving them at preschool for the first time?
I could not have imagined myself in this situation. This, I'm a giant baby situation.
If you axe me, I need to build a bridge and get over it.
I think I might have PMS.
