I've briefly mentioned it earlier, but this is one of the most depressing subreddits I've ever seen
r/GriefSupport
On the first glance, it may appear helpful and wholesome, but in actuality, it's a masochist depression circlejerk cult of people who went insane from grief.
A person shares their loss or asks for help, but dozens of people in the comments tell them how grief is forever, it never gets any better and suffering is awesome. And then they get openly and proudly hostile towards anyone, both online and in their lives, who genuinely wants to give support or suggests getting help. Strangers online, psychologists, friends and family, even other grieving people.
Their pathology destroys them and their still living loved ones and they know it.
