Dear Navin ,
Sorry to know that you are suffering
.You should not take any drug
from medical store for your condition without prescription of doctor because it can lead to severe consequences .You can consult your nearest psychiatrist
or homeopathic physician for further management.Online prescription for such a case could be hazardous so do not try to get medicine online.Please consult physically and then only start treatment for the same.
Hope this clears all your doubts,
