Depending upon where you're going you may not need to ship things. Remember, if you have stores like Bed, Bath & Beyond or Linens & Things near you and near the school you're going to, ask them if they can set you up with placing a college order at the other store. You may be running a bit late for them to do it easily, so try and go down to one sometime this week and see if they will do it for you.
Why is this useful? It means that you save a boatload of money on shipping large, annoying items such as bedding, dorm supplies, and other brik-a-brak since all you have to do is go to the store out there with receipt-in-hand and pick up. I've done it a few times and it is a ~lifesaver~.
I also second VA's suggestion to "eat food." Just because you're on your own doesn't mean you can't fend for yourself. Personally, I had these to start off with and it should give you enough options when it comes to making some basic food...
* Stockpot
* Saucepan [just in case]
* Saute Pan
* Cookie Sheet / Baking Sheet
* Collander / Strainer
* Cutting Board
* Chef's Knife
Very rudimentary stuff (and open to plenty of criticism) but you can get a lot out of those tools. Pasta and rice should be a snap (and far better than ramen), and if you have a kitchen nearby in a dorm or apartment you can easily cook most meat, fish, or fowl. You don't have to do anything fancy but you can get a lot of mileage out of this sort of stuff. Also, check online for various, simple recipes or go bum around friends and family for easy stuff. You can supplement the list however you want later on. If it's too much for you, you could buy one of those rudimentary kits at, say, Target and elsewhere, but make sure you're getting what you're paying for.
Otherwise, I found that having my own microwave to be immensely useful, especially since most college students treat dorm microwaves and kitchens like shit. I also loved having my own mini-fridge and actual mini-freezer, but I loved to cook. $100 for something I can fill with meat and live off of for at least two months without resorting to buying food on campus? Heavenly. But that's not for everyone.
I'd give more suggestions but I'm a bit of an odd duck. I pretty much have 3x the amount of stuff people tend to put in their own rooms and yet everything looks normal. You don't need all the crap I have so I'm not going to suggest. I do recommend, however, to keep garbage bags, plastic wrap, sandwich bags, and napkins/paper towels around though. Maybe even toilet paper. This is just a worst-case scenario sort of thing, because I've had situations where Housing just didn't bother to clean up the kitchen, bathroom, or anything else for weeks on end. I'd rather have those essentials than be like my friends who...well, tried to do without. Didn't end well...did not end well at all...
