Starting to feel down..

Formerly Mrs D S

which is extremely concerning to me.  I am still working full time.. with a 3 year old .. trying to keep up the house and meals etc.  Except I am finding myself going to work - being somewhat productive.. getting home and being too tired to play with my DD ... too tired to clean up - I am still cooking.  The house looks a mess.. I feel like my DD and DH are having this awesome bond (which I am THRILLED about), but I am also feeling left out. 

This probably sounds crazy to people, but I feel like I am just sitting here waiting.  A part of me wants to play and have a great time, but then when I get in the situation I am too tired and the Dr told me to rest as much as possible (bc of contractions).  The mixed emotions are really playing with my head, and I am just starting to feel so down all the time, and Im nervous that I dont know why. 

 Anyone else??
