So sorry to hear that!!
From what I understand it's not a bad thing for her to have a fever unless she's lethargic. It is important to let her immune system do it's job correctly, and also remember babies tend to naturally run higher fever temps than adults do.
If she really seems to be struggling beyond her and your comfort, you could try the wet sock method. I've heard it works wonders, and is a drug free way of helping LO's out.
