One shaken Lehman shareholder had a million reasons to mourn the loss of his former company yesterday.

Actually, 6 million.

“I’ve lost more than $6 million overnight,” lamented David Shorr, standing in front of Lehman Brothers’ Midtown headquarters as hundreds of stunned and depressed workers milled around him.

“I’m wiped out,” said the 49-year-old Upper East Sider.

Shorr currently works as a “wealth adviser,” a senior vice president, at Morgan Stanley. But he spent years at Lehman before that – and said his stocks and benefits from his tenure at the now-defunct investment powerhouse are all worthless.

Shorr could muster only a slight smile as he read a large sidewalk placard, with an unflattering depiction of Lehman CEO Richard Fuld, being signed by angry employees and onlookers.

“What the hell was he thinking?” asked Shorr, who placed much of the blame on the hard-charging executive who has been one of the country’s highest-paid CEOs.

When asked if he had any hopes of recovering his nest egg, Shorr just shook his head and waved his hand.

“It’s gone,” he said with a sigh.

Fueling the anger at Fuld are reports that the CEO refused multiple bailouts offers, including a chance, as recently as August, to sell a 25 percent stake in Lehman for $4 billion to $6 billion to Korea Development Bank.

Several Lehman employees leaving their offices yesterday declined to be interviewed. But one desperate veteran worker met the request with one of his own: “Can you pay me for my story?”
