All of them, this is a QuickTime event. You have to feel out what they're looking for. You have to hit the buttons in order and with the right timing

First - that sucks. Show empathy and active listening, see if they have more to say. Let them get it out

Next - you have to decide, are they more upset, or more stressed

Upset - story time, show sympathy. Keep it light on the details, and don't try to draw comparisons - keep it at the emotional level.
Then advice time - again, keep it brief and vague

Stressed - advice, lay out options rapid fire and see if they latch onto any. If they don't, story time - tell them about similar situations, without drawing emotional comparisons, where you got past it more easily than expected
