I think the community is called Hive thrifted.
People are selling all sorts of stuff there.
Gives you a bunch of stuff to do if you start clearing out your hoarded items.
Catalog them, make pictures, invent a nice backstory for each item and share it.
Build a community around it. Start seling the items on real life fleamarkets, you might make some decent friends there.
Also reach out to those friends who never call you in 5 years, and ask them kindly how they are doing and how they are feeling and what has been going on in their lives. You are clearly not alone here on hive, see all the comments!
Also sorry for the long comment here is a potato in the making:

Bro the part when u call them and ask they are, thats a good methood too. They would act like hey, what u need sometimes is like that and u only pass by saying a Hi from ur old -Friend-
