Life is so full-on that sometimes there isn't any time to sort out the little problems, and before you know it, they've grown into giant problems. So if need be, go to a counselor and let him or her help you out.

Is it identical to say "So if there is need/necessity" to replace "So if need be?" What kind of construction is "So if need be?" Why does it use "be?"

Besides, is "out" in the above optional? What does it mean? Thanks.

"Need be" = if necessary (it's a subjunctive form); "out" is not necessary, and some would say it's not very good form.

Thanks, Philip.

But how is "if need be" derived? That is, where does it come from? I've never seen this kind of subjunctive form before.
