I agree with steps mentioned to get her onto a more autonomous path. I'm thinking, based upon those that I've seen this happen with is that it's not the validation that's needed. It's the equivalent of being in a victim mindset of sorts. The mention of insecurity makes sense as it includes a lack of sense of independence.

Her crisis of the day/hour/week/month belongs to her. It's even ok to say,"I don't know." "what do you want to do?" "how are you going to handle this?"

Conversing with you might give her some sense of crutch. But it's not a set of wings.
