Since you are already on treatment from psychiatrist at NIMHANS.. if there is no good response better consult again, because
1) Your history would have been taken in detail and summarised, during first consultation and you need not repeat everything again to another doctor
2)It's a frequent possibility that you might not respond to treatment initially..
if nothing works out, you may also request for change of unit or take online consultation.
Next Steps
maintain patience, follow whatever has been said to you by both Psychiatrist and Psychologist
Health Tips
do yogaasana and regular physical exercises
