After her notorious performance at the MTV Awards and countless pictures of her sticking her tongue out, Miley Cyrus' mental state has been in question.  Some have speculated that she's the next in the line of former child stars like Britney Spears and Amanda Bynes to have a break down, to which Cyrus admits that she does have issues, mostly as a result of her workaholic attitude.

In an intervew for the UK paper Sunday People a few weeks prior to her infamous duet with Robin Thicke, Cyrus was candid about the issues she's developed by being in the public eye since she was 14.

“I have so many f***ing issues. I am so f***ed up – everyone does dumb  stuff when they are messed up. I don’t have a normal life. I take a  hiatus every now and again but I’m not good at that.”

Cyrus also went into detail about her life, which she explained is so chaotic and busy that she sometimes only gets 45 minutes of sleep, and gets little exercise beyond some yoga and thirty push-ups a day,

"All I do is work, so I eat to live and to keep going."  Cyrus continues, "I suppose I am a workhorse. I love being in the studio and when I take  vacation I get so bored."

The biggest thing to take away from the interview is something that we've known for a while, that Miley wasn't as good as the character she portrayed on "Hannah Montana",

“During Hannah Montana I think people knew I was acting. I’ve never been able to  hide anything, a bit like Justin Bieber."

While there is no doubt that Miley is passionate about her work, a common complaint about Cyrus' actions is that she's still viewed and marketed as a singer primarily for young girls and teens, regularly winning Teen Choice Awards.  Some stars like Brooke Shields have spoken out against Miley's recent actions, while others like Selena Gomez have praised Miley's performance as "awesome".  Now that Miley has admitted to her personal issues, it will be interesting to see the direction she and her career take if/when she takes some time off to refocus.
