"Been crying myself to sleep. Taking a zany trying to pass out. Goodnight," the 20-year-old singer wrote to one of her 12.9 million followers.

After deleting the tweet, Miley then posted, "Never mind. Realized I’m just an idiot & somehow I butt tweeted my conversation. Missing home."

The Party in the USA singer has been on the road and things haven't gone as smoothly a she hoped, having suffered food poisoning amid her hectic schedule.

"I flew from L.A. to New York, then to Miami, back to L.A., then to Canada, then to L.A., then to New York, then to London, then here, and somewhere in between I went to the Bahamas too," she said in a recent interview in . "My life is totally crazy!"

Sounds like she should probably slow down!
