I am a hoarder, flat out, no question.
I would say I struggle, but most of the time I'm too busy/lazy reading to do anything about it. I'm in a productive mood right now (about 3 or 4 days a year), so hopefully I can stretch it for more days. I watched Hoarders for years and it did help me some, but not enough to make a difference.
At least I've differentiated between cleaning the house and clearing the house. I have to clear my house before I can clean my house. (I just made a mini breakthrough. I changed the "the" to "my" in the preceding sentence.) Small step to taking ownership of "my" situation.
