Hi Rubi,
I think before starting any medical treatment it should be clear that symptoms are due to specific
anxiety disorder or physical problem. Medication do not cure anxiety bot keep them under control. i think you are student and how much possible you should avoid anti depressive medicine due to there side effect. First or all you should maintain healthy life style, get enough sleep,good nutrition,exercise, some personal time,,thinking positively. There are some
psychotherapy treatment like CBT(Congentive behaviorral therapy), Counseling should be done. Benzodiazpines also useful should take 30 minutes before exam start of exam. Dear do not take exam as a
stress take it as your normal activity or as a hobby.
