it is what it is

1

That's life; expressing resignment to a situation or set of circumstances, usually without complaint

Unfortunately the insurance doesn't cover that. Sorry, but it is what it is.

2

Let it be; accept the fact and let the matter rest.

3

Used other than figuratively or idiomatically: see it, is, what, it, is. This thing has its own distinct nature; this thing is itself.
