advice please :’)

hello. Im trying to help my mom get rid of stuff. The hoarding has run in my family through generations. Finally stopping with me. I’m trying to help my mom because my little brother feels weird having people over at the house and it’s driving my dad insane where he won’t walk through certain parts of the house because it brings him to tears. It’s all Disney stuff. Yes u heard me, Disney. From thousands of dollars in Mickey ears to thousands in lounge-fly purses. She won’t get rid of any bc they are “worth money” but she won’t sell them. It’s frankly destroying my family to where I don’t even want to come home anymore. I love my family but growing up in this has made me a neat freak and it drives me insane. Just wanted to give some background.

What I’m trying to do is ask if anyone has advice on getting rid of things. She doesn’t even know what’s under what. Just any advice helps it’s really crushing me. She seems to be in denial about it since she has grown up in it for generations.
