Two weeks after the death of her boyfriend and Glee costar Cory Monteith, Lea Michele has returned to Twitter and thanked her fans for their support.

"Thank you all for helping me through this time with your enormous love & support," Michele wrote, sharing a sweet, snapshot of herself with Monteith.

"Cory will forever be in my heart," she said.

Monteith was found deceased in his room at the Fairmont Pacific Rim hotel in downtown Vancouver, British Columbia, shortly after noon on July 13. He had checked into the hotel on July 6 and had been expected to check out on the 13th. When he had not done so, hotel staff checked his room and found him deceased. He was 31.

The BC Coroners Service confirmed Monteith died from a mixed drug toxicity, involving heroin and alcohol.

The post-mortem testing, which included an autopsy and toxicological analysis, seem to confirm this was an accident.

According to reports, Michele was blindsided by the news.

"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. "She didn't know he'd started using again."

Last week, Fox announced that production on Glee would be pushed back until August in the wake of Monteith‘s sudden death. The postponement subsequently moved the show’s Season 5 premiere back a week, to Sept. 26.
