You know how on LOST, they have to go back and re-live the traumatic experience of the plane crash? It was one of the worst things they ever went through, and they have to do it again. They know it will be painful. They know it will hurt like hell. They know there will be carnage. And yet, they know there is no getting around it. So they brace themselves, try deep-breathing, and just hope that this time isn't as bad as the first time . . .
Yeah, that's pretty much EXACTLY how I feel about my upcoming labor.
