I respect your position as a parent to do what you feel is best, but I disagree with this. If I were in your shoes, I would ask her to predict what she was scared would actually happen.
It’s easy to be “generally anxious” of what might happen. To do so is not overstating or exaggeration, or at least not in our frontal lobe — the part of our brain responsible for higher reasoning and “simulating reality” of what we expect to happen — but when we’re afraid, our frontal lobe is subdued. Instead we are in a much less critical thinking state, (you’ve heard, I’m sure, of “fight or flight mode”) where we are well-suited to make flash decisions without thinking… by considering only hunches, fears, and “gut feelings”.
And when we are responding to gut feelings, on issues that involve prediction of what’s going to happen… we’re not using the best of our mind. But when we engage that mind to make a prediction, we’re forced to re-process our experience through our frontal lobe. Doing so helps us calm down and look at the situation rationally.
And looking at the situation rationally, gives us far more power than simple fearful reacting, doesn’t it?
