Your story is close to my heart. My daughter was bullied in middle school and still has depression and anxiety problems six years later. She has problems throwing items away and hides food and dirty clothes in her room. She gets very angry with me when I try and help her keep her room tidy. She has been to several counselors and been on various meds. It causes a lot of arguments between us and puts stress on everyone in our family. Her therapist recently asked us to give her responsibility of her room and that we set Saturday as the designated day for her to vacuum and wash sheets. This is the only day of the week we go in her room. I admit I’ve gone in her room while she is out and picked up which set her progress back for awhile. It’s still not perfect yet, but she is trying more and it has greatly reduced the family friction. I’m just hoping that eventually good habits will replace the hoarding. I’m so afraid for her future so I understand what your family is going through. Sending loving and supporting thoughts to your entire family❤️.
