Stevie Nicks wrote a letter to the cast of 'Glee' after Cory Monteith's death.
The actor tragically died earlier this year from a drug overdose, and the Fleetwood Mac singer reached out to his co-stars after growing close to them after an episode in 2011 inspired by her band's music.
She told the Sunday Telegraph newspaper's Stella magazine: "I said, 'Forgive me if I'm stepping into your personal space. I lost my godson to an overdose last year- he died at a fraternity party - so I understand how shocking that is'.
"When what happened to Cory happened, I just was sick for days. Honestly, just sick. It's just so prevalent. It's everywhere. It's worse than when we were young."
The star has battled with drug addiction in the past - from a 10-year cocaine habit to sedative clonazepam which was prescribe to help her overcome it - and she knows it cost her the chance to settle down and start a family.
She added: "That was stolen. And that's not forgivable, ever ... [But now] I think I am stronger than a lot of people. And I knew then, as I know now, that I still have so much to do."
