Final year burnout. I know the textbook answer, I just can't apply it to myself

I can recite the criteria. Emotional exhaustion, depersonalisation, reduced sense of accomplishment. I can tell a patient what to do about it. What I cannot do is stop feeling like a fraud who will fail her practicals, stop crying in the hostel bathroom after a bad viva, or sleep more than five hours. My friends are the same. We joke about it, which is probably its own symptom. There is a counsellor at college. Nobody goes because everybody will know. Did anyone here get through a professional course with their mind intact? What did you actually do, not what you would advise someone else to do.
