The psalmist doesn't only ask to be rescued. He asks to be shown a way, direction in the middle of the crisis, not just relief once it's over. Notice the timing too: answer me quickly, my spirit fails, comes right alongside the request for guidance. He's not waiting until he's calm and clear-headed to ask for direction. He's asking for it precisely because he isn't calm and clear-headed, because the urgency itself is part of what makes him need to be shown rather than left to figure it out alone.
