In my opinion, a lot of stress comes down to time management and also expectations. There is the expectation that the teacher can carry the student to success and while that may be true for many students, it is impossible for you to provide what every student needs. Better time management has certainly helped reduce my stress levels already, and better preparation in regards to lecture will help ease a lot of the strain, but identifying and accepting the fact that you are human has done wonders for my mental health.
