And who could blame her? Pilloried from all sides, she manages the intractable Brexit process with a divided public, irascible Party, no Commons majority, and a disloyal Cabinet snapping at her heels. Every day must be purgatory.
Whatever her critics say, however, Theresa May is a decent person with a huge sense of public service and a work ethic second to none. It is these characteristics, combined with a desire to atone for her disastrous General Election campaign, which has led everyone to assume she will carry on. There are no more General Elections for her to fight. Taking us out of the EU successfully was to be her legacy.
But will it? The constant pounding from critics and the seemingly insurmountable hurdles at every stage of the Brexit negotiations must be taking their toll and perhaps she has had enough.
Here are a few pointers to support this view. She is now standing up to her Brexiteer colleagues in public and in private, some would say recklessly, caring less and less about the consequences for her premiership.
She is prepared to extend the customs union transition period to 2023 to sort out border issues with Northern Ireland. Essentially she has told Rees-Mogg and his merry band of European Research Groupers to shove it.
She will take on the Lords with a series of make-it or break-it votes in the Commons to overturn their amendments to EU exit legislation.
Rumours of an Autumn election are also bubbling under the surface.
It is now or never for Theresa May and never looks an increasingly enticing option to watching Brexit drift onto the rocks. At least nobody could say she didn’t try hard enough before reaching this point.
