Selena Gomez is reportedly finding it really difficult to move on from former boyfriend Justin Bieber. The two started dating in 2010 and have had an on-and-off relationship until 2014.

Gomez had cancelled her Revival world tour after dealing with anxiety, depression and panic attacks as side effects of lupus. According to a report in Life & Style, the former couple's rocky relationship took a toll on the former Disney star. An alleged source said: "While Selena does suffer from lupus and other health issues, that's not the reason she went to rehab. Her biggest addiction is Justin."

"She became a different person around him. She was extremely jealous and possessive and felt like she had to keep up with him to keep him. So she would drink and smoke, and then she got into weed and partying," the insider added.

Another source said: "Justin is such poison to Selena. Even when he isn't around, she is still self-destructing because of him. Her addiction to Justin is what everyone is afraid is going to take the ultimate toll. Justin takes her to a dark place mentally, and she really can't let go."

Gomez had previously revealed that she is unhappy with the constant scrutiny about her relationship with Bieber. She told W magazine: "I'm so exhausted. I honestly am so done. I care about his health and well-being. But I can't do it anymore."

"To me it was: I'm 18, I have a boyfriend, we look cute together, we like that. Then I got my heart broken and I cared. Because people had no idea what was going on, but everywhere it was a million different things. I was kind of in a corner, banging my head against the wall. I didn't know where to go," Gomez added.
