why do I feel like crying??

Went through the same thing too! Oh and let me tell you, the worst thing to watch on television is Animal Planet. I cried over the animals on there for two weeks.
I cried over the house, the kids, the husband, the way my clothes fit, my stomach and the worst thing was that I cried out in public one day because I couldn't find what I was looking for.

Hugs to you! There is an adjustment period to go through after surgery.
