And it not being socially acceptable to talk about your own childhood is super alienating. Sometimes people want to know why, and any answer you can give them is going to be off putting.

One of them said something like, "it doesn't bother me that [Friend] was in residential mental health treatment, I just wish they wouldn't talk about it ALL the time".

The other replied, "Well, that was all of last year for them. So when they say 'when I was in treatment,' it's like when you say 'last year'."

Like… if you open a coffee shop and run it for a while and it makes you happy but then stuff gets too expensive and stressful and you want to do something else so you close it, it’s a “failed” business. If you write a book or two, then decide that you don’t actually want to keep doing that, you’re a “failed” writer. If you marry someone, and that marriage is good for a while, and then stops working and you get divorced, it’s a “failed” marriage.

The only acceptable “win condition” is “you keep doing that thing forever”. A friendship that lasts for a few years but then its time is done and you move on is considered less valuable or not a “real” friendship. A hobby that you do for a while and then are done with is a “phase” - or, alternatively, a “pity” that you don’t do that thing any more. A fandom is “dying” because people have had a lot of fun with it but are now moving on to other things.
