Morning girls, I need to let this out

Yesterday was one of the worst days since my DD arrived. I could not stop crying. All day it was, I was so down. Everything just became too much.

I was supposed to go to SIL#1's baby shower and had spent the weeks before sewing a quilted play mat for her. I had known about the shower weeks before as SIL#2 had told me about it. I got the invitation on Wednesday night by phone and got myself so worked up and was so anxious about attending I could not stop crying.

Needless to say I did not go anywhere, as my head looks like a tomato after a crying session, and stayed inside most of the day.

Today I feel a lot better, like a totally different person again. My DD must have known it was a bad day for all and slept from 12 to 7 and is now back down for a sleep again.

Does anyone else ever have days like this? Am I normal?
