Has completely taken over my life

I have been on summer break now for about 2 weeks. I honestly think I have done more cleaning in these 2 weeks, then I have done in the year that we have been in this house. I feel like a crazy person, but I can't stop until I have finished what I set out to do.
I have a feeling it will be getting much worse when my sister moves out next week, her room will be the nursery. Plus, I have my baby shower on Saturday.. I hope this phase can hold out a little longer.
Anyone else feeling like this?
