Troubled HAPPY DAYS alum ERIN MORAN has gone into hiding after her personal life spiraled out of control.

As The ENQUIRER reported previously Moran who shot to stardom as Joanie Cunningham was kicked out of the trailer park where she was staying and is now holed up in an Indiana hotel room writing a book about the difficulty of being.

In recent months, Erin, 52, has been hotel-hopping around town after becoming homeless and even got into a drunken brawl with her mother-in-law!

"Erin thinks the best thing for her at the moment is to just stay in," a source

"She’s working on an autobiography, which she hopes will settle (her) debts.

Every time she ventures out, whether it’s to a bar to grab a drink or even to the supermarket for some groceries, Erin seems to land in hot water.

"Her husband Steve (Fleischmann) has been helping her stay out of trouble – but they just don’t leave their hotel room anymore," the source revealed.

Just weeks ago she was scheduled to tape an episode of DrPhil but didn’t show up for the taping.
