@hazardwarning I think waiting to decide what comes next is a good idea - wait until there's clear water between you and this job, if it comes to it, maybe even take a short break.
What could be worth doing now is mind mapping (or outlining) what you enjoy about this role, and what you might want from a future job, just to get your subconscious mulling it over.
Doing that, and maybe getting your CV up to date, will help give you some control back too..
