My son is 24 years old. He left is btech in the final year in 2018. He even got the campus placement but left the job in between in march, 19. He started writing english rap & wanted to become rapper. Even he left the house in 16th july with out telling anything to us. He came back home in patiala on 30th august. He seems to be under deep depression as his behavior has become very aggressive. Please help us in this regard.
