I'd talk to her physician. I'm not too clear on the time scale between her missing days for the flu and the depression beginning, but I do remember reading that some flus are followed by depression, to the point where some people feel suicidal. It's good that she's talking to a counsellor, but she may need more than that. Also, she may not be telling you how severe the bullying is. Can she still study at home? In our province, we have courses that can be purchased from the province, with all the information needed, and the student works at home at his or her own pace, and then when ready, schedules a proctored exam and writes the exam and all papers. The exams and papers are corrected by an independent grader, and if the child chooses this option they are able to receive a diploma, not just a GED. If your daughter is bright and can do the work, perhaps letting her learn at home is better for her. Kahn Academy and others have excellent materials, as well, and you can always hire a tutor to work with her on classes you cannot teach (if any). Be sure to get her her higher maths and sciences and other classes as needed for the career she wishes to pursue. (Some universities require both French and German to study history, for example).
