Thank you for your question. To answer your question regarding treatment, the only way to get your friend into treatment is if you decides to go with it. If he is suicidal or has intent of hurting others, then he may be involuntarily hospitalized. To convince your friend to see someone on an outpatient basis I suggest two things. First, inform him of your concerns of his symptoms. Describe to him that his current symptoms are similar to someone who may go see a doctor when they are ill. Second, offer going to the first appointment with him if he is nervous of going by himself. Please let me know if you have any questions.
