Los Angeles, Sep 5 (TIWN) After Justin Bieber opened up about his struggle with fame and addiction to "heavy drugs", several of his friends, including Miley Cyrus and Ed Sheeran, have come out in his support.

Earlier this week, the "Sorry" singer shared an Instagram post through which he reflected on how growing up in an unstable home and becoming a global star at 13 turned out to be physically and mentally stressful, leading to drug abuse and suicidal tendencies.  Celebrities, including Sheeran, Cyrus, Sean Kingston and Khloe Kardashian, left comments on his post -- some thanking him for sharing his story and some showing him love and support. 

"Friends from the beginning, here until the end," Cyrus commented.  Khloe wrote: "This is beautiful! Thank you!! We are so proud of you!! I needed this! God bless you always."  "Wow thank you for the testimony. I sure needed this... God bless you forever my lil brother," posted Kingston, who collaborated with Bieber on "Eenie Meenie" in 2010.  "Love seeing this so much man! Wow," commented singer Cody Simpson, who collaborated with Bieber in 2014 on "Home to mama".
