3 years in a depression

OMG, I still can't understand how these people live in this mess. I was depressed, but my house was the tidiest place on earth in that period of my life.
If you watch the program hoarders , They say right at the beginning How many millions of people Suffer from this problem... Watch that program for a few episodes. You'll see it piled up to the ceiling to where they're crawling on five feet of stuff to get to from room to room..
