“Barring a miracle, I’m going to be in my car,” she said.

Ms. Jarrin is part of a hard-luck group of jobless Americans whose members have taken to calling themselves “99ers,” because they have exhausted the maximum 99 weeks of unemployment insurance benefits that they can claim.

For them, the resolution recently of the lengthy Senate impasse over extending jobless benefits was no balm. The measure renewed two federal programs that extended jobless benefits in this recession beyond the traditional 26 weeks to anywhere from 60 to 99 weeks, depending on the state’s unemployment rate. But many jobless have now exceeded those limits. They are adjusting to a new, harsh reality with no income.

In June, with long-term unemployment at record levels, about 1.4 million people were out of work for 99 weeks or more, according to the Bureau of Labor Statistics. Not all of them received unemployment benefits, but for many of those who did, the modest payments were a lifeline that enabled them to maintain at least a veneer of normalcy, keeping a roof over their heads, putting gas in their cars, paying electric and phone bills.

Without the checks, many like Ms. Jarrin, who lost her job as director of client services at a small technology company in March 2008, are beginning to tumble over the economic cliff. The last vestiges of their former working-class or middle-class lives are gone; it is inescapable now that they are indigent.

Ms. Jarrin said she wept as she drove away from her old life last month, wondering if she would ever be able to reclaim it.

“At one point, I thought, you know, what if I turned the wheel in my car and wrecked my car?” she said.

Nevertheless, the political appetite to help people like Ms. Jarrin appears limited. Over the last few months, 99ers have tried to organize to press Congress to provide an additional tier of unemployment insurance. But the political potency of fears about the skyrocketing deficit has drowned them out. The notion that unemployment benefits discourage recipients from finding work has also crept into Republican arguments against extensions. As a result, the plight of 99ers was notably absent from the recent debate in the Senate.

Senator Debbie Stabenow, Democrat of Michigan, is now working on a bill to help those in the group, a spokesman, Miguel Ayala, said, but the chances of providing them with additional weeks of benefits seem dim.

“It’s going to be extremely hard to pass,” said Andrew Stettner, deputy director of the National Employment Law Project. “We barely got 60 votes to keep 99 weeks, so it’s even harder to get more.”

Other ways of helping the long-term jobless might have a better shot of succeeding, Mr. Stettner said, like a temporary jobs program or assistance for emergency needs.

Ms. Jarrin ping-pongs between resolve and despair. She received her last unemployment check in the third week of March, putting her among the first wave of 99ers. Her two checking accounts now show negative balances (she has overdrafts on both). Her cellphone has been ringing incessantly with calls from the financing company for her car loan. Her vehicle is on the verge of being repossessed.

It is a sickening plummet, considering that she was earning $56,000 a year in her old job, enjoyed vacationing in places like Mexico and the Caribbean, and had started business school in 2008 at Iona College.

Ms. Jarrin had scrabbled for her foothold in the middle class. She graduated from college late in life, in 2003, attending classes while working full time. She used to believe that education would be her ticket to prosperity, but is now bitter about what it has gotten her.

“I owe $92,000 for an education which is basically worthless,” she said.

Last year she moved to Brentwood, Tenn., south of Nashville, in search of work. After initially trying to finish her M.B.A. program remotely, she dropped out because of the stress from her sinking finances. She has applied for everything from minimum-wage jobs to director positions.
