It literally is policing it…how do you know that argument didn’t make someone feel depressed? And how does their being depressed over an argument detract from your own depression, just because yours is worse doesn’t mean someone else can’t be depressed to a lesser degree over something that you personally consider unimportant. Situational depression exists. To me this whole thing is just weird tbh Mental health isn’t a competition and sadly there’s more than enough MH issues to go around.I don’t think it’s policing conditions or belittling somebody else’s sadness when you are so depressed that you physically cannot get yourself out of bed but are listening to somebody say they’re depressed because they had an argument with their boyfriend.
