You know what Missy...sometimes I have those melt down moments or days I don't feel like I'm living up to my expectations and I don't have any of the good excuses that you do. I am not pregnant, I have not lost either of my parents yet, etc. I can't say for certain but you seem like a pretty good mom, and looks like you were an awesome daughter and I would bet you do pretty well in the wife category as well.
I agree with Kelly, you were due. Allow yourself time to have the BLAHS and then try to regroup.
Hugs to you!
Karen
