It sounds like a serious case of separation anxiety. Realistically, she will probably not be able to transfer to a new school within the next few days..let alone by next semester. She'll probably have to go through the same stressful, and tedious and unpredictable application process she went through last year, just to get into yet another school. And she'll be doing it, while trying to attend classes etc. at the current school, unless she totally drops out. And that has it's own problems in itself. And after all of that, what's she going to do if she hates the new school as well?
I guess the question is, does she want to risk taking time off from school before she gets started? Not to mention she may lose all of that money you've invested so far such as fees, books, housing, etc. She also risks losing any credits she's earned which could mean she'll spend up to an extra year in school just to get a degree.
I suggest she sticks it out for the semester or until she actually gets accepted into a school/program she likes. She can begin sending applications out now, while she continues with her current school. In that window of time (between now and being accepted somewhere new), she'll know for sure if she's not cut out for this school, or if it's just a tough case of Freshman jitters.
I suspect, as soon as she meets friends she's simpatico with, or even finds that "special someone" if she doesn't already have one, she'll more than likely come around and think the school is just "great". I guess, short of the writing program being a total stinker, or she changes her major, I think she's just going through adjustments and will be fine. She just might take a little longer than some kids.
Meanwhile, send her lots of care packages, call her lots (maybe even a couple of times during the day until she makes some friends or feels more secure), or at least until she starts giving you hints to back off, and visit as much as possible.
As for the embarrassing moment in the cafeteria...tell her about my friend who was the school's mascot one year. At the big homecoming game, he was doing all sorts of acrobatics and rah-rah's to get the crowds going at the big aftergame bon fire during a live newscast. He didn't know he got too close to the bon fire and that his "tail" was on fire while he and some cheerleaders were interviewed. Right in the middle of the live report, he smelled smoke (so did everyone else), started screaming, burst into a huge ball of flames, knocked down everyone standing there on live t-v with him, and began running like a maniac screaming wildly, until some people from the crowd jumped him and smothered him with their tail-gating blankets. AS hideous as it all was, everyone, I mean everyone in the crowd and even the reporter was totally cracking up. The whole thing was so surreal, it almost seemed like a planned comedy routine. Unfortunately, he was far from laughing.
Luckily, he was not burned though the school's official costume was totally trashed! He was embarrassed! He got teased and terrorised for a long time about it. But he got over it. Funny in retrospect, but horrible things ironically always are if you get through them unscathed.
