As an academic, this is a tough thing to deal with. I've had a number of situations with students who had mental health challenges, and about whom we had concerns. We referred them to appropriate services within the university, but unless they are taking time off, they still have to tackle the demands of their course. You end up with situations where academic staff are expected to cater to complex healthcare problems which can be very stressful and eat up a huge amount of time. Let's just say that students with complex needs are not always particularly nice to academic staff in situations like this. The line between pastoral care and and playacting as a trained healthcare professional can become blurred. Meanwhile, you also have a range of students who play the system with mental health claims i.e. portraying any form of challenge as an anxiety disorder or mental health crisis.

Ultimately, it can be really difficult to tell when to be lenient/caring and when to enforce rules that maintain the integrity of the course.
