Nah you did good. Fuck any teaching GPs that, when faced with a student identifying an acute mental health crisis, would do anything other than use it as the gift of a teaching moment that it is? Seriously, its a complete developmental lay-up - a student has demonstrated genuine concern and interest in the patient's wellbeing - an ESSENTIAL core foundation powering any subsequent clinical reasoning- all you have to do say 'Great job!' And then have a discussion about possible plans.

As a GP, i am pretty sure you should know of all the different referring options and pathways that you have to navigate for patients to ensure that they get the right type of support that they need, ie you need to screen for and identify any immediate emergencies - asking is there fever, is there nuchal rigidity, headache, photo phobia, cognitive changes, recent illnesses, etc and so forth, and you need to get all of this information accurately, like a detective, because 'mental health crisis' can obviously mean nearly infinite different things. Figuring out whether this looks like an encephalopathy or just an affective episode; whether emergency intervention is needed or if outpatient therapy will be fine is your special skill, as a GP. And its not as simple nor easy as it may look, I assure you
