Same as anyone else, get an appointment with your GP, he/she would be able to direct you somewhere. Depends how bad your anxiety is, sometime some simple counselling would do the job, and your college/uni should have a counselling team or sth who woudl almost be able to offer counselling to you quite quickly. Coz getting CBT or sth else is a long long waiting list. Also, coz there is such short supply on this kind of this, sometimes so GPs would offer meds at a very early stage due to the lack of option they have, please say NO to the meds, try everythign else first, only take this option when you no longer able to control yourself naturally. It has been a nightmare for me so far... but I didn't have a choice...
