Well first of all what dosage have you started on ? You should always start on the lowest does possible when beginning anti depressants and give it 2-3 weeks for the side effects to subside.
I'm taking lexapro however anti depressants do not change your mindset and are no miracle cure you have to accept yourself and change your whole mindset to realy see change. The lexapro helps for my depression more then anything and it keeps me on track and motivated to tackle my anxiety
