How to tell it has outgrown reading

Practical markers, not spiritual ones.

The anxiety is there all the time rather than only around exams. You are having panic attacks. You have stopped attending altogether and you are hiding it. You cannot sleep at all, or you are sleeping through everything. You are using stimulants, energy products in quantity, alcohol or anything else to study or to sleep. Eating has stopped being ordinary, or has become something you are controlling.

And the first one again, because it belongs at the top of every list in this course. Thoughts of ending your life, or the thought that failing would be unsurvivable. That is today, not next term.
