Is 「出なくては。」 the same as 「出なくてはいけない。」?


I guess the novel I'm reading (「キッチン」 by 吉本ばなな) will be a source of many
questions.

The part I want to ask about now is the passage where the main character is
thinking about moving house. The passage is the record of her thoughts and
contains some sentences that are not complete. In two places she's thinking:

> でも、ここを出なくては。

and later

> 出なくては。

I'm guessing maybe 「出なくては。」 is a shortened, incomplete form and normally has
something after は. Is it the same as 「出なくてはいけない。」 and the meaning is "I have
to leave"?

(Let me know if I need to post more to give context.)
