Yes! We seem to be walking in the same shoes... though I am not well put together so my purse doesn't match.
Just this morning I was thinking about getting rid of everything and starting over! I actually did that about 4 years ago and it doesn't work.
I go through phases sometimes, or have reasons to get the apartment in shape like you did. Sometimes I think the tidy times are the abnormal times. Like an attempt to control things as I feel more in control, more positive, more capable, etc when everything around me is orderly.
I think maybe so much of my energy goes into maintaining that public image and when I get home I have little or nothing left; no energy or interest in me or my surroindings.
