I have a student who exhibits low self-esteem, signs of depression, and is completely disorganized. His father died last year in a rather violent manner and he lives with his mother and stepfather. I would like for him to have regular appointments with the school social worker, but his mother is completely against the idea, which worries me more. I have tried to help this student and have made some gains but he needs more than me. How do I convince the parents?
