She was haggard and looked aged beyond her years, and along with her history of drugs and alcoholism, she couldn't get work in show biz.
She had a very sad life after her acting gigs dried up, and it's really TOO sad to delve into.
May this troubled soul rest in peace. We will remember her always as the bouncy, bubbly, smiling little gal in "Happy Days", which were, in effect, her Happier Days.
Leni
Amen.
