Not everyone had a great 2015. While some experienced success, fame, love, and all the stuff memories are made of, others had a more stressful time. Some celebrities will be more than glad to bid farewell to 2015; especially those that had rather public freak-outs. Whether online or in front of a camera, some stars are especially looking forward to the New Year. Here are the most outrageous celebrity meltdowns of 2015.

Lamar Odom
 

The former NBA star and estranged husband of Khloe Kardashian was apparently on a wild road -- one that led to dangerous consequences. Odom was found unconscious at a brothel in Las Vegas, reportedly having overdosed on as assortment of drugs. The Kardashian family rushed to his side, including his wife. It's been a long, slow recovery process since then, but Khloe has remained firmly by Odom's side. Make no mistake about it: this is one meltdown that could have been downright deadly.

Miley Cyrus
 

Is it a meltdown or a publicity stunt? After multiple highly publicized feuds (including an unforgettable one with Nikki Minaj), it seems that MIley has been upping her weirdness factor to critical levels. From dressing up as a stick of butter for her onstage performances to posing fully nude (and provocatively staged) in numerous magazines, Cyrus has left many people scratching their heads. If it's all for publicity, it's genius. If it's not -- well, that butter costume is pretty concerning.

Aaron Carter
 

The younger brother of Backstreet Boy Nick Carter (and a pop star in his own right) has not had a fun 2015. He went from publicly declaring his undying love for ex-girlfriend Hilary Duff during an interview (who did not take too kindly to his constant talk about her), to snubbing her on social media. And to top off an already unpleasant year, Carter once again got far too personal on Twitter by ranting about a recent devastating break-up. Maybe his New Years Resolution should be to use social media less often? Or at least not talk about his exes in public (Hilary Duff for one would probably support that resolution). 

Iggy Azalea
 

It seems like just yesterday that Iggy Azalea was riding high and dominating the music world. So why has she gone mysteriously silent? It's another case of too much social media being a decidedly bad thing for some celebrities, as this meltdown proves. Iggy's issues started on Twitter, when she angrily quit after some people used the social network to body shame her. The comments enraged her, and she went on an epic Twitter rant about how vile people can be online. But that wasn't the end to her social media misery; despite her claims, the rapper was still seen online. That is, until a paparazzi picture led her to once again storming off from social media sites. Can't we all just get along?
