Patient discussion about secondary malignancy

Q. I have met my close friend after 3 years. She is showing some signs of high depression. How can I help her? I have met my very close friend after 3 years and she is very depressed. I am worried that she is showing some signs of high depression. She talks all rubbish and negatives these days which is filled with that nonsense hopelessness. She was fine and going good when I left her and now she is completely negative in her behavior and also very depressed. She is not able to enjoy my company. She had lost her weight and her eyes reflect the bluntness. She keeps silent most of the time. How can I help her?

A. I think first you must talk to her and find out about when and how this started. Take her to all the places where you both used to go. She might have come across difficult phase in these years which would have made her depressed and she may need a support to bring her back to normal way of living. We cannot say that this is a depression which would get cured by just talking and knowing the reasons but you must help her to fight back for the thing she had lost. If there is no desired result, then do consult a physician.
