K.S.
It is easy for the response to be "she just needs to tough it out." But I don't think you have given us enough info for me to feel comfortable saying that. Nor does it seem she is equipped with the skills she needs to "tough it out". The key here is to peel back the layers and find what her true concerns are and then work at them together. Maybe you could fill in some information as to what the teacher thought. Does the teacher feel she is struggling academically? Does she need extra support for reading, writing, or math. My son struggles with writing and has sensory processing problems which have affected his entire school experience. So he has gone to occupational therapy to improve his skills and made it easier for the school to set up some classroom modifications. Or does the teacher see she is having trouble fitting in or being accepted by the kids? Then you can work with her on that issue. At the point you are now, it seems to be a jumble of stress and anxiety complaints, so between you and the teacher you will have to help her sort through the mess and zero in on some things she can learn and control. Keep in mind, that this may also be a bad fit for her in terms of the school or particular classroom.
