Dear Mulan
Sorry you are having problems
I should say that pineal cysts or pinealomas usually cause headaches,visual changes,occasional dementia like changes,rarely psychiatric changes,despite producing serotonin derivatives. It's main function is circadian rhythm control (sleep/wake cycle).If you are concerned you shouldrepeat MRI,but talk to psychiatrist ,maybe you should face your fears first
Medschool is hard,but not impossible. If you chose it because you loved it do not leave,especially you are one of best students.
Tell us why you chose medschool?
why do you think you can not share?
What is it you are trying to disregard?
talk to us,there is no judgment here,and people are friendly even though they don't know you
Good luck ,best wishes
