Lea Michele is still coping with the shocking death of her co-star/boyfriend Cory Monteith and reportedly went to a California retreat to deal with her grief and pain.

Over the Labor Day weekend, Michele spoke to grief counselors at Esalen Institute, a spiritual retreat based in Big Sur, Calif., the U.K.'s Look magazine reported (via Radar Online.) Her late Canadian beau died at 31 of a heroin and alcohol overdose July 13. 

At the retreat, she did yoga and meditation for several hours a day.

"I think Lea wants to be able to keep herself busy on a daily basis. That’s why she agreed when one of her oldest friends (identified as one-time Glee actor Jonathan Groff) suggested leaving Los Angeles behind and heading to a spiritual retreat to help her move on," the insider said.

"I imagine she’s doing everything she can to keep things together,” the source continued. "She’s such an optimistic person and I know she’s trying everything she can to live life to the fullest and keep her spirits up but sometimes she needs support and guidance -- that’s why her weekend at Esalen was so perfect. Lea needs time but every day, with so much support, she is getting stronger."

At the time of her boyfriend's death, Michele had a difficult time coping.

"Lea completely lost her mind," a close friend told Us Weekly. "She went crazy, screaming and crying until 3 a.m."

"Lea has been inconsolable and feels like she's been hit by a truck," the friend said back in July. "She didn't know he'd started using again."
