A lot of these I don't think are different phrasings, they're different in meaning as well. A closer rephrasing with similar sentiment is: "No one cares" All the phrasing you provided are combinations of: 1) not applicable to me/us 2) we can't do anything about it For anyone struggling with empathy, imagine you're feeling frustrated with something, you share with your coworkers, one replies publicly "no one cares" and everyone else laughs. Then the next day the thing that was frustrating you happens a number of times and you can't say anything because it's clear that everyone doesn't care.
