I'm a spouse of a hoarder. Whenever I tried to look for solutions, I get "Here's why people hoard" articles. I never heard a single story about a hoarder overcoming it (TV shows don't count), which indicates that you must either just live in it or leave...neither of which I want to do.
However, these "Success stories" give me hope. So thank you.
BTW: I do realize it may come down to that binary choice.
