Ask your counselor to intervene on your behalf. She should call up the admissions office and beg them to help you because of her mistake. She may be able to get somewhere if she asks for help to make up for her mistake. You shouldn't have to suffer because of her mistake. Press her (politely) to try this for you. You never know... I worked at a university and exceptions are often made to rules.
Go enroll in community college now. Smaller class sizes and you won't have 70,000 to pay back in loans by the time you graduate. Once you get your AS degree or AL, transfer to a university. Enter as a junior, and by that time you'll be taking mostly easy classes anyway since you will have gotten your hard sh! done at a comm. college where the professors are much more accessible and more focused on teaching than their research anyway.
