Why do I feel this way?

I got a call from my aunt this morning, saying she was going to be in my neighbourhood this afternoon and would like to drop by and see us. We haven't seen this aunt in quite awhile so I should be really happy she is coming by. But I'm not. I'm tired and had hopes of the girls going for a nap this afternoon so I could too. OR at least hopes of reading my book all day and doing nothing. Well now I have to clean my house, shower, get dressed and entertain someone for the afternoon. Don't get me wrong. I love my aunt and really am happy to see her, but why pick the one day that I don't have to do housework and have the possibility of an afternoon nap? *sigh*

Now I just feel angry at myself for being so selfish and sad that I'm going through these emotions. Need to get cleaning some more and compose myself so I can portray that happy, perfect housewife image. AARRGGGG
