I agree with all that has been posted. Being a friend, listening, joking, etc are what she needs. She needs a purpose to get out of bed each day, does she have a pet? Listen to her, support her, be there for her but don't take on her problems. Sadly, one person's depression can drag a lot of caring people down so please be careful. In the end your friend has to decide she wants to get well or she wants to continue to live her life as it is.
