“Thank you all for helping me through this time with your enormous love & support,” she wrote. “Cory will forever be in my heart.”
Lea and her “Glee” family will return to work next week for the first time without Cory, who played Finn Hudson on the show.
Show creator Ryan Murphy told E!, "[Lea] felt that the best thing for the cast and crew was to be together and to get back to work and be together every day and talk about our memories of him. So we decided to do that with Lea's blessing and we're going to go back to work and have grief counselors on the set for two weeks because people are really hurting."
Last week a source told HollywoodLife that Lea is struggling now more than ever. “Lea is getting worse -- the shock is wearing off now and the reality is setting in. She’s been having horrible anxiety attacks where she feels like she can’t breathe.”
"Glee" star Lea Michele has tweeted for the first time since Cory Monteith's death, posting a pic of herself and Cory along with a message thanking fans.
