Casey Anthony's private diary has been made public and her shocking confessions may help convict her of murdering daughter Caylee.

"I have no regrets, just a bit worried," alleged baby killer Casey wrote in a journal entry dated just 5 days after Caylee went missing.

According to documents released Wednesday by the Florida State's Attorney office, Casey also wrote, "I completely trust my own judgment I know that I made the right decision. I just hope that the end justifies the means.

"This is the happiest that I have been in a very long time."

Casey, who is awaiting a trial, is charged with first-degree murder in 2-year-old Caylee's death but has pleaded not guilty.
