Why is Ann Thinking about Trash?

At the beginning of the movie, we're introduced to Andie MacDowell's character, Ann Bishop Mullany. She's sitting with a therapist in a clean, spotless living room, where she's explaining her worries, which lately have been about the trash.

I too have been very sick over the condition my house is in. Like Ann's character, on the outside I seem all right. On contrary, on the inside, I'm angry and mad, and the only thing I can pinpoint about what's wrong in my life is the messy chaos happening in my bedroom, in my car, in my kitchen, in the bathroom... Everything's a mess and it's dirty and there is trash that has not been taken out for a week.

Can somebody tell me what the connections are here? Why was Ann talking about the trash?
