You tutors will not know, unless a) it's an active problem or b) you tell them...
I have quite a colourful mental health past (EDs), and no one really knows, and if they did, I'm not sure they would care too much.
If I'm being frank, medicine can be stressful - hell this last fortnight has been horrible, but it's the only way to qualify, and if you don't try, you'll never know if you could have done it...
After this week, I have to admit to having given serious thought as to whether I can complete the course, to say my exam stress reaction was pathological would be an understatement, but then again the end of year 2 is unsettling - hopefully preparing to leave pre-clinical med behind and moving in to the unknown of clinical school... I'm going to give it my best shot though, even if I die trying!
