Vivian: Okay, I don't want to do anything that you don't feel comfortable with. This is your decision. Just remember that even though you feel okay right now, once you start taking interferon you might begin to feel depressed. Do you remember what you felt like the first time you took interferon therapy?

Vivian: Those were the first signs of depression. Why don't we begin interferon therapy and keep monitoring for depression together? We can routinely give you the BDI to follow your depression symptoms. If you begin to feel sad and tearful again, will you call us?

William: Yeah. Sure. I can do that.
