Therapy is the most important part of the process when it comes to helping a hoarder truly change. There is a saying...you can take a bottle from an alcoholic, but they are going to get another bottle. You can't just empty a hoarders home or they will fill it up again. They need to work through this process and learn why they acquire and have difficulty in letting go. There are many reasons people hoard, so finding the right therapist is extremely important. Finding one that can come to the home is very rare, but if you can, excellent!
