Hello practo user I can understand the difficult situation he is facing currently . Inability to focus on work , low mood , low appetite are all indicative of some underlying stress which is aggravating these symptoms. It is suggested that you ask him to go for regular walks or exercise as it will help him feel better physically and mentally as well . Try and spend some quality time with him and do some activities of your choice together . Try and involve him in conversations and keep his mind occupied. Try and ask him to eat small meals every 2-3 hours as maintaing a healthy diet will be beneficial for his overall health . It is advisable that you seek help from a clinical psychologist for a proper diagnosis and treatment plan for the problems which will also teach him adaptive skills and techniques for the same .
