Hello doctor, My best friend has been suffering lately from deficiency of vitamin B12. Our doctor informed us that he suffers from depression and anxiety because of vitamin deficiency. Is it possible? His dad died when he was 10, so I observed that he takes it so seriously when he feels that he is not fulfilling his duties to his mother and sister. He is trembling and shaking because of subconscious thinking. I know his mother and sister, and they are proud of him. How to convince him for it?
