Nellie Riether, a single mom from Ringwood, N.J., faces a stark choice: raid her retirement savings or uproot her kids from home and move in with her sister.

"To be honest, it's mortifying and embarrassing at 46 years old to say I'm going to have to move in with my sister," she says. "Emotionally, it's a bit of a failure."
