Hello, You have to know what is causing him depression & anxiety & then only he can get a better treatment. Commonly it occurs due to stress, anxiety, some developing pathology(disease) / illness in his system, some medications, substance abuse, addiction to certain drugs. Get him evaluated by a Counselor or a Psychiatrist. In the meantime give him home made food, adequate sleep, keep him away from stress. Regular exercises, outdoor drives, music, reading good books, dancing effectively divert & distract patients from anxiety. Get him a medical check up done so that if there is any illness, it can be treated at the earliest. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Nupur K, General & Family Physician
