Here are some great resources that I have personally checked out. With the exception of the ebook (written by yours truly) I receive no payment if you access any of these resources. I’m always happy to promote the work of good people who are dedicated to helping clutterers and hoarders.
This book is a step-by-step guide to gently clearing clutter. It is very detailed and shows you how to tackle every area in your home.
Help for Hoarders
This site has some great resources for those in the UK, but their forum is a great place for people from anywhere to connect with others and share questions and helpful strategies.
The Clutter Movement
This group provides online support, coaching, guidance, consultation, and training for individuals, family members, and professionals affected by clutter. They provide virtual webinars, topic specific forums and live chats, and are working with other agencies and groups to remove the barriers to treatment and support.
Unf*ck Your Habitat
Strong language, great articles! If you want to connect with a site that tells it exactly how it is with no holds barred, check out this out. I especially like her article on depression: The Depression/Messy House Cycle
