At my school, workloads are immense and the pressure to succeed is high. With that comes an increased rate of sadness or frustration in students. Often in class or in the dining hall, I will hear students complain about their homework, stress over an upcoming test, and even break down and start crying.

However, I think one very interesting thing to note is when depression can actually be diagnosed. At what point does someone go from just being sad and stressed to actually being depressed? If you're comfortable sharing, how has this boundary been crossed or defined in cases of depression that you have seen?
