Thanks for your query. I understand your concern with depressive symptoms. Sertraline
is a standard antidepressant that is prescribed to alleviate depressive symptoms. However, antidepressants take atleast 6 weeks to start acting. Hence, you need to be patient. Many other effective classes of antidepressants like SNRI's and TCA's are available in addition to psychotherapy
(eg cognitive behavioural therapy). So please do not lose hope.
