I would say that the professionals know what they are doing, if they feel that your friend needs the medications then that is what that person needs. Mental health issues are misunderstood by many people. Anxiety can be very disabling. If you broke your leg, you would go and get it put in a cast and get treatment for it, it's the same for mental health issues, treatment is required. Some people need medications and psychotherapy, and if your friend needs that and it works then all good!
