<p>If I’m reading you correctly, you really want NU but are having second thoughts about committing, which is not unusual for many high school students about to choose between two colleges. </p>
<p>I started writing a response to all your points but have decided that you’re just getting cold feet. You need to do what you feel most comfortable with but I would hate for you to wake up at Berkeley in October and wonder why you gave up the opportunity to expand your horizons.</p>
<p>Good luck in your decision!</p>
