Nightmares. Insomnia. Early wake ups and binge drinking. After Game 7’s devastating loss to the Red Sox, we Yankee fans are showing all the signs of depression.

Consider just a few snippets of the conversations this reporter – and diehard Yankee fan – had on the streets of New York City yesterday.

“I didn’t sleep well, thinking about the game,” said a 14-year-old Yankee fan, Yan Saavin.

“I was drinking the whole game – and after, so I could sleep,” said another fan, John Davidson.

And by far the most common response to Yankee inquiries: “I don’t want to talk about the Yankees.”

In defeat, we Yankee fans are a surly bunch.

It’s not every loss that makes so much history: This was not only the worst collapse in playoff history, but a defeat at the hands of the hated Red Sox, a team that had never beaten the Yanks in a postseason series.

The TV images from Yankee Stadium on Wednesday night said it all. Nearly everywhere the camera turned, fans stared wide-eyed at the field. Some pulled their hats over their faces. Others watched the celebrating Red Sox through the bars of their fingers. At least one man with dream seats slumped on the dugout roof like a corpse.

“They just kind of collapsed inside. They didn’t know what hit ’em,” said a Yankee fan and psychologist, Stuart Fischoff. “It was almost like some invisible nefarious force entering the game.”

He almost makes it sound like the Bambino’s curse has found a new victim. But we have no other answers for how it happened. Maybe a dark force and a weak bullpen is the best explanation we can muster.

Matthew Kelly, another fan, sensed the foreboding after the Game 4 loss.

“I had insomnia every night after,” he said. But after Game 7, “I felt an odd sense of relief.” And he slept like a baby.

A Long Island College Hospital psychiatrist, Dr. Ravi Amin, said that many of his colleagues stumbled around the hospital yesterday with “a tinge of sadness on their faces.” But he said Yankee fans still struggling to cope today might need to re-evaluate the place of the team in their emotional lives.

“Review your own relationship with the game, with the team, and what it’s doing to you now. Be aware of it,” he said.

That may be well and good for Dr. Amin, a Yankee fan and kind-hearted doctor. But the rest of us may instead be out looking for a little revenge: Red Sox fans are everywhere, and we’ve just lost our best taunting material. Some Red Sox fans seem to expect that with the American League Championship Series over we’ll roll over and join in their fight for a World Series victory.

No way. In a Yankee fan’s perfect world, trash talk in the future will sound something like this:

Red Sox fan: “We beat you in that 2004 ALCS.” Yankee fan: “And yet, still no championship.”
