NEW YORK (TheStreet) --  Many Americans are "stressed" about the state of their retirement savings, according to a Merrill Edge survey. But the younger generations are the most nervous of all.

"The younger generation, the people that have more time to plan for retirement, generally the millennials and Gen Xers, they seem to be more stressed than people that are already in retirement," said Paul Vienick, head of Merrill Edge (BAC) Self Directed & Merrilledge.com. "The reason is because the retirees have made a plan, they have executed for that plan and they have been saving and working with a financial solutions provider or doing their online research."

Two out of three Americans expect to be stressed about money in retirement, based on their current saving levels, according to the spring Merrill Edge Report. The biannual survey of more than a thousand Americans with investable assets between $50,000 and $250,000 also found that the folks with the most time left to get ready for their golden years -- Gen Xers and millennials -- are "most likely to anticipate a financially rocky retirement."

On the other hand, the survey found that 59% of current retirees say they are not stressed, because of how they prepared their finances over the years. Along those lines, the report found that 73% of retirees who have saved believe they will have enough money to last the rest of their lives.

That's a far cry from the 43% of millennials who say they are counting on financial help from loved ones if the need for it arises in retirement. That figure is much higher than the 9% of all other respondents combined who expect to need such aid. The big reason for the disparity most likely comes from the fact that 43% of millennials say that they "feel behind their peers" in either financial stability, saving for the future or their income.

"The millennials are very interested in seeing what their friends are doing, how they are doing it, and with so many tools being available, they are really starting to dive in, utilize those tools today to make sure they are prepared for their retirement," said Vienick.

Of course, millennials also have a somewhat different vision of how they will spend their post-employment days. According to the survey, 66% say that their ideal retirement includes "traveling often" and 54% say the same about "living near loved ones".  By comparison, 62% of Gen Xers, baby boomers and seniors have the travel bug, while 46% want to live near loved ones in retirement.
