What would Anne Frank have written if she had continued writing in a diary after her hiding place was found?

American high school students, who are studying the Holocaust, are sometimes assigned by their teachers to write a few entries in an imaginary diary, writing as Anne Frank might have done, if she had continued her diary after her hiding place was raided by the Gestapo.  I believe that Anne Frank did continue to write in a new diary after she was sent from Auschwitz to Bergen-Belsen in October 1944.  I am basing this on the fact that many inmates of the Bergen-Belsen camp did, in fact, keep a diary in which they described what it was like in the camp.
