Hi, Welcome to HealthcareMagic Forum.
You should be taking your Son to a Psychiatrist
so that he can examine him and Prescribe antidepressants and Psychiatric Counseling. Else there is no way he can come out of it. He needs to stick to his treatment plan and go for regular follow up. He needs to stop drinking and smoking
if he does. Ask him to exercise regularly, avoid stress, sleep for 8 hours daily and eat healthy nutritious balanced diet which should include fresh fruits and green leafy vegetables. He should be practicing relaxation techniques
like Yoga and Meditation
and learn more about depression
, this will help him understand his situation better and will help him stick to his treatment plan.
Hope I have answered your query, I will be available to answer your follow up queries.
I Wish him Very good health.
