I have heard that mentioning mental health issues (depression, self harm, eating issues) in medical applications in any way is a bad idea. I have tried to write my ps while avoiding this experience (where I learned about my close friend's troubles and how it impact me because I felt helpless to solve anything) but it just isn't working; this experience is a big part of my I want to become a doctor specifically and not a biomedical researcher. Is it possible to discuss this in a way that works, or should I avoid it completely and try to focus on other stuff?
