Thanks for your query. I understand your concern with non-response to medication. I would like you to appreciate the fact that treatment at this stage would be fruitful throughout your life considering you are young rather than developing a full blown depressive disorder that would hamper your life in long term.
We have a wide variety of antidepressants including SSRI
groups of antidepressants. You can discuss with your psychiatrist
if you do not respond even after 6-8 weeks on a medication. Psychotheraapy techniques like CBT/cognitive behavioural therapy can also be considered. Wish you good health.
