I am still traumatizes from high school after almost 30 years. I had no extra-curricular activities but I had to travel far for the school of choice (I was an ESL student). Waking up at 5:45, 90 minute travel one way, then 8-9 periods ending at around 5PM. Get home at 7 and then do homework.
Then the never-ending pressure of midterms, finals, and regents exams.
