Miley Cyrus is heading for a breakdown?

OHMYGOSSIP — Miley Cyrus isn’t coping. The singer is struggling with the emotional fallout of being dumped by fiancé Liam Hemsworth this summer and the constant criticism from haters who have made her the national punch line.

So, Miley has turned to destructive behavior like nonstop partying and random hookups.

“She doesn’t have many real friends and is constantly messed up,” says a source.

“She never wants to go home, never wants to be alone and doesn’t want the party to end. The way Miley has been acting is a cry for help. She’s been acting erratically and has a screw-it attitude. Everyone is worried now that Liam is gone. She’s a mess without him.

“She was so in love with him and really took it hard. She’s been going out a lot, trying not to think about Liam. She was happy focusing on Liam in the beginning, but she’s narcissistic.

“She eventually turned her attention back to her image. She’s obsessed with who’s talking about her, what they’re saying and how she looks. Liam couldn’t care less about any of that. She’s always looking for male attention. It’s uncomfortable to be around.

“She’s partying to mask her true feelings. And she’s really unhealthy — she barely eats. She monitors what everyone says about her and lets that influence her opinion of herself,” says the source. “If she continues acting out at this rate, she could be headed straight for rehab. It’s sad.”
