The actress is back to work on Glee and apparently, getting back into a routine is helping her heal.
"Feel so good to be home," she Tweeted yesterday, along with this solemn photo of herself on set as her character Rachel Berry.
The 26-year-old also recorded her first song for the new season of the Fox show, in which Cory's character will be written off.
"Couldn't have picked a more beautiful and perfect song to start the year with," she Tweeted Monday.
Lea made her first public appearance since Cory's July 13 overdose from heroin and alcohol last weekend, when she put on a happy face to attend Jamie-Lynn Sigler's baby shower in Beverly Hills.
