This is nothing new.
25 years ago, when I first started teaching there was a significant study that showed that law students had more diagnosable mental health issues than either medical students or graduate students. Further, the study determined that unlike their graduate counterpart most law students mental health issues were directly related to law school. For many, the stresses that occur in law school can seem unmanageable if one is not adequately prepared for the demands of law school. This is not an intellectual issue. Law school is not hard because the material is inherently difficult. Law school is hard because there is so much at stake and, only 1 or two exams a semester, and no specific instructions on how to do well. How to study effectively, how to write law school exams are not taught. Furthermore, few schools have pre-matriculation summer bridge activities. I f you are admitted to a school that has one - attend. Otherwise, participate in quality summer bridge activities. You would not go to school in a foreign country and expect to do well without learning the language and the culture. Don't risk your mental health or your academic performance because you failed to fully understand the law school language and culture.
