Tuition and Books

My journey in law school begins.  I have officially paid my first semester's tuition and I have ordered books for all but one of my classes.  That is a ton of money, and I still have to pay for the Spring Semester in a few short months.  I don't know what I have gotten myself into, but I hope that somehow and in someway this will help me.  If anyone out there remembers the fears of starting law school while working full time, please let me know if they fear of being crazy goes away once classes start.  I just keep thinking this is a crazy thing to do, and that I am crazy to be working full time and taking classes three nights a week so that I can get a J.D.  Other people do this, so surely I can to.  Maybe if I just keep telling myself that I can make it through the next few weeks until classes actually start.
