I just get out of the hospital and the Dr. found out I got a very bad yeast infection and I need help !!?

My problem here is that the Dr. gave me Diflucan 150mg once a day for 5 days and on my daily basics at home I take Xanax 1mg for anxiety.. The problem is that there's interactions on those medications and Im getting crazy because i want to be free of this horrible infection that it doesn't let me sleep but on the other side I need my Xanax to calm down and be relax!!! Can PLEASE somebody help me?? I will really appreciate all your feedback's.. THX in advance
