Miley Cyrus is having a hard time right now! She feels like her career is completely falling apart, while all the other girls with whom she grew up are thriving!

Miley Cyrus has been dropping drastic weight and flashing her privates — and now we might know why. The 19-year-old starlet is frustrated with her career and is feeling like all her competition/friends are leaving her in the dust.

“Miley doesn’t like seeing her peers, like Vanessa Hudgens, Demi Lovato and Selena Gomez, getting roles and opportunities that she believes she should be getting,” a source close to Miley tells . “Miley is more frustrated with the lack of offers for films like Journey 2 and Spring Breakers.”

Adds the source, “She was at one point bigger than all of them combinedand doesn’t like playing second fiddle. Add that with the weak response of LOL and she is at a standstill in her career, which she believes should be in the stratosphere.”

Miley was in a huge rush to get out of the Disney Channel world, even branding herself as this “Can’t Be Tamed” adult star. However, did she force the transition too quickly? Do you think she should be nervous about her career — or will she be just fine?
