Since Demi Lovato endured a public meltdown back in 2010, she has been candid about her struggle with bipolar disorder and bulimia. Now the former Disney sensation is opening up to Self magazine about her road to recovery.

I've spent the past two years getting over an eating disorder and issues like self-harming and bipolar disorder, Lovato says. Unlike a person who doesn't have these problems, I have to work on this stuff every day. I'm reminded of that whenever I eat or feel down.

Lovato, who is set to appear as a judge on the X-Factor, has admitted to vomiting up to three times a day in the past.

''I'd make myself sick up to six times a day, Lovato told Fabulous magazine in April. My mom was worried, but because I was going through puberty I was having growth spurts so she assumed that was why I was thinner.''

The 19-year-old has revealed that some days are still difficult.

I cannot tell you that I have not thrown up since treatment, in an interview with MTV. I can not tell you that I have not cut myself since treatment. I'm not perfect. This is a daily battle that I will face the rest of my life.

Lovato is one of many female stars who have recovered from an eating disorder. Here are five that have managed to do so.
