Be patient with your parents! The path you have chosen is very different from that of your friends going to "regular school." Your parents' experience will be very different also. They will not get to shop for your dorm room, or your back to school clothes. They will not be able to take three days off from work to get you settled into your new school. They will not be able to call their child on the phone those first weeks that he is away. Unlike parents of kids going to "regular school," their apron strings will be snipped all at once on the day you leave.
This has been a journey for you, but you have not been alone. Your parents have been behind you for eighteen years, so please patiently smile as they lecture you to be careful for the next few months. Give mom extra hugs, and carve some time out to do special things with your parents and siblings before you go!
Congratulations on your accomplishment! Stay in shape, run a lot. Be safe and enjoy the rest of your senior year. The big packet of forms will come in the mail. Relax until it gets there, but once it does, hop on it, because some things may take some time.
PS Tell your parents to be sure to change their IRS deductions at work ASAP...more than likely you will not be a dependant for them for 2011.
