Hello and welcome to Healthcare Magic. Thanks for your query.
It is unlikely that the anti-depressants could have been the cause for your depression
or its worsening. However, certain anti-depressants can cause drowsiness
and sedation, which could have probably prevented you from being active and fully functional.
I hope that you are having the anti-depressants tapered down under the advise and monitoring of your doctor. If you are not inclined to take medication, then I would suggest that you try psychological therapies like CBT, which can be very effective for depression.
Wish you all the best.
Dr. Jonas Sundarakumar
