てばかりはいられない

てばかりはいられない means "I can't just keep doing this": the situation won't let you go on doing only one thing. It is てばかりいる, "do nothing but", with いる in the negative potential いられない, and it follows the て-form of a verb.

The verb is usually a passive or unproductive state – crying, worrying, feeling down, resting, relying on others – and the next sentence often says what has to happen instead. It is said to yourself as resolve, or to someone else as a push.

てばかりはいられない or てはいられない

てはいられない says you can't afford to do the thing at all right now. With ばかり, doing it is fine; doing only that is not.

Usage notes

These go beyond the basic form.

は, も, or neither

も can replace は with the same meaning: てばかりもいられない. Without either particle, てばかりいられない is a little more casual.

Polite form

いられない becomes いられません.
