Hoarding

Ahh hoarding, you some how that show is so addicting. It scares me that I understand if to a certain extent. I can understand holding onto things that have sentimental value. For me personally I would be more anxious if I was buried alive in my own house. How does it get to that point? When does your anxiety over letting things go overwhelm your anxiety for control.. Or how does clutter give you the illusion of control? I mean in watching this show, much of what is being hoarded is truly trash... How does that happen? How/ Why are we all wired ao differently that some anxiety leads to overzealous cleaning, while for some it created a world of walls?
