Concur with all the above. Your job is to be a good listener and try to determine if she is experiencing anything more than just the typical difficulties of first semester freshman year. Have you been to visit? Going to parents weekend helped me see that my son was doing better than his very short and unsatisfactory phone calls suggested.
My middle son came home a lot at the beginning of his freshman year at the not very far away State flagship. Once he found his people, he came home much less.
I have heard many stories of kids that were ready to fill out the transfer applications at this point in freshman year, but stuck it out and by the end of the year were very happy with their college. Of course, others transfer and find a much better fit.
