Just because she said those things doesn't mean that you absolutely didn't get the job. A lot of people are nervous at interviews, and you never know how you compare to the others who went in. Most people leave interviewers feeling very uncertain or certain that they won't be getting the job. Did you feel like you were extremely nervous? Were you aware that you may be giving off that vibe? If you don't get this job, use it as a lesson to prepare for future interviews. Remember that although interviews should be taken seriously, just be yourself and try to relax. Remember that everyone there is a human being, just like you. Many times even they can get nervous!
