Lindsay Lohan is in "hell" after splitting from Samantha Ronson.

The "Mean Girls" actress and her DJ girlfriend called time on their tumultuous relationship on April 3 after almost a year together, and Lindsay admits she is struggling to cope on her own.

She said: "It's absolute hell. It just really hurts, the whole situation is sick."

Lindsay, 21, was turned away from a party at Los Angeles' Bar Marmont where Samantha was playing a DJ set late on Friday night, and admits the scenes which unfolded were "humiliating".

The actress was barred from entering the bash by five security guards - reportedly hired by Samantha's family to keep her away.

Lindsay told Us Weekly magazine: "It was the worst night of my life."

Following the incident, Lindsay took to her blog on social networking website Twitter and accused Samantha of cheating on her and taking drugs.

On April 4, Samantha had the locks changed on the Hollywood Hills home she lived at with Lindsay.

A distressed Lindsay said: "I'm not a bad person and this is what happens. I was raised to treat people well, and I'm so tired of this drama."

The actress admits she feels "so alone" since splitting from the 31-year-old musician, and claims Samantha's friends - including Nicole Richie - have now turned on her.

Referring to the incident at Bar Marmont, she explained: "I'm a 22-year-old girl who's in love. I felt like I was in 'Mean Girls', but worse - 'Mean Girls' was a movie."

It has also been claimed Samantha tried to break up with Lindsay many times over the past month but backed out when Lindsay threatened to kill herself.

Meanwhile, Samantha has denied claims she is seeking a restraining order against her former girlfriend.

It was originally claimed the DJ's mother Ann and sister Charlotte had visited a police station on April 6 to enquire about ways to keep the actress away from Samantha.

Her lawyer David Bass said: "Samantha has no plan to request a restraining order. There is no basis for one."

Lindsay is currently being comforted by her mother Dina and sister Ali, while her father Michael - who has publicly admitted he dislikes Samantha and called for Lindsay to end the relationship - is en route to Los Angeles to see her.

He said: "Break-ups are never pretty and they're never easy. I'm here for Lindsay any time. I've cleared by schedule to go to her. At a time like this she needs someone standing by her side. It's time for Lindsay to resurrect her life and career."
