Feeling bad about something you can’t change is bad for your mental health.

and naming your feelings is the first step toward restoration

Probably beats being in denial over it and pretending you like it.

And identifying problem you dislike is a good first step to find a strategy to solve it at least in part.

Deciding that you can't change something is the first and last step towards failing to change it.

Which is not a problem if you choose not to worry about it.

"It's uncool to care about things" is, fortunately, not a compelling argument for people who care about things.

This tangent does not seem likely to go anywhere productive.

That’s a reductionist and wrong reading of the argument I made.

You said "can’t change". I observed that deciding you can't change something is self-fulfilling. Your argument from that point still relied on the assumption that you can't change it.

Before you decide not to care about something, you are supposed to make a deep assessment to see whether you can change it. It is only after you’ve determined that the thing can’t be changed that you can choose not to care about it.

You can care about things, but it seems preferable to care about that which you can change
