I dealt with this as a freshman in college, too. I didn't turn 18 until I was already several weeks into my freshman year. Very immature and felt out of place living on my own away from home for the first time. My freshman year was essentially a waste of time and money, and I nearly landed on academic probation. It wasn't the freedom that was my enemy. It was the lack of structure and study habits I was never forced to learn in high school because it all came natural to me without having to study.
Not sure if another year of age and teenage wisdom would have made a difference for me, but I graduated as an honor student when all was said and done. The learning curve was just much steeper for me as a result. Could be the same thing that is happening with BHH.
