Irish, I guess I would have to say "W, I'm sorry that you are hurting and I'm here if you want to talk". Nothing more. There's no need to go into detail about the depression or her friends. She has to figure that stuff out for herself. Keep your reply short and sweet.
As for her exiting the tunnel...nope. They go through periods of clarity and that's when you get messages such as the one you did.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
