Don't know how to approach my mom about this
Before my mom moved up here to Maryland from 4 hours away in Virginia, she had a pretty good life in an apartment where she could walk down the hall and see her friends. She was pretty independent and was driving herself where she needed to go and despite being more introverted, she was fairly outgoing. Her health took a dive and she ended up with diabetes, neuropathy, arthritis, breast cancer, kidney problems, and vertigo issues that caused her to fall. One time she collapsed in the middle of thenight and wasn't found until 36-48 hours later (because not even she knows when it happened - she has no recollection). That was right in the prime of covid and she ended up becoming more recluse and she used online shopping and QVC/HSN as her friends and shopped and shopped and shopped for completely unnecessary items. She ended up becoming a hoarder, albeit a quite organized one, and when it came time to pack things up, it was a nightmare because there were boxes upon boxes of unopened items. I think I filled 8-10 of the extra large Depends boxes with brand new in the wrapper Lands End clothing. She fought tooth and nail when we said she can't bring all that up because the mini apartment my brother had built in his house did not have the space for all of the things she wanted.
In the end, she had one last hospitalization down in VA and we had to do a rush move up here (this was in the works for 3 years). She has been in her mini apartment for nearly a year, but now she's getting back to some of those shopping habits. She's recluse again here because she can't drive and she also is constantly cold so she doesn't want to go to the main part of the house because it's 70 while she has her place at 78 degrees. My brother and SIL say a package comes nearly every day for her. While she had lived her before (she moved in 2008) nearly all her former friends have since passed or moved away. Only one friend is still here, but they don't really do much.
I can't have my mom become a hoarder again - my brother doesn't want to have all that stuff in the house. Whenever we talk about things with her, if she doesn't agree, she gets very defensive and beligerent and I can't handle that. Meanwhile, I'm the one taking her to her gazillion doctor appointments and I spend hours with her each time but I don't know what to say. I really think my mom needs some kind of counseling, but she says she feels OK and doesn't need to talk to anyone. She is on an antidepressant though, which is prescribed through her primary doctor.
I don't know how to handle this or if I should since it's not even my house. Help?
