The medicine you are taking is the right choice for you. But I have some queries-
How long you are taking these medicine?
Because for severe depression
you need to take those for 9 to 12 months and that also should be ragular. These kind of depression or nervousness
comes due to imbalance in the Neurotransmitter
(Chemicals that act on nerve
and brain). These medicine supplement those chemicals from outside actually or functionally. Therefore when you stop medicine those symptoms reappear.
However in difficult cases medicine can cure upto 50 to 60 %,
You can use Psychotheraphy, counselling
which will change your approach to several problems in life which will help you 20 to 30%,
Finally your surrounding social-economical pressure, relationship, other stressful events contribute to the rest 10 to 20%.
so if you approach in this manner it will be easy for you to get the solution quickly and then getting back to your normal healthy life will be just a matter of time.
