Inside the storm, that's all your mind can manage to see. It reverts back to past survival of different storms, looking for similarities and differences to survive the current one.

Personally, what I'm going through now sucks. I've been through worse, though. Much worse. Came back from something I thought would kill me; it was the worst pain I've ever felt, even to this day. I still feel it. So, in my mind, "I lived through that, I can live through anything."

You might look back on this moment later on, and think the exact same thing. Only time will tell.
