Before Mark Salling committed suicide this week, he had previously attempted to take his own life in a shocking cry for help, a friend of the Glee actor revealed exclusively to RadarOnline.com.br br "I messaged him after he slit his wrists and I just asked if he was okay, and he directly said no. I was just like, well, how do I respond to that," the pal told Radar of the disturbing exchange last summer.br br "Do I think somebody should've stepped in and done something? I don't know," the friend told Radar. "He did open up to me. When he was acting depressed, I was thinking, sure everyone is depressed. I didn't take it seriously enough."br br LAPD received a missing person report on the Glee star. Six hours later — around 8:50 AM — police discovered his body.br br PHOTOS: Secret Pedophile For Years!
