Joanna Fortune: My son only attends school in the afternoon, doesn't have friends and avoids lunch breaks 

The combination of lack of sleep, difficulty with peer interaction, poor and inconsistent engagement in school and his general lack of responsiveness to your efforts to get him there on time makes me wonder about his mental health status

Joanna Fortune: "Loneliness and peer isolation are contributing factors to mental health issues. This is another reason I would strongly advise that you bring him to your GP, who can do an initial mental health assessment and refer him to local services if necessary."

My son is in first year. He started well, but after the October midterm break, he began coming home early and missing days. Now he goes to school in the afternoons. 

He hasn’t any friends in school and avoids lunch breaks. His school has been great about encouraging him. However, I am worried that he won’t be able to get up in the mornings to take his summer exams.
