Chris Brown has to stay another two months in rehab in Malibu, even after showing a recent positive change in behavior, CNN reports.

Chris was sentenced to three months of in-patient rehab in November, and while there his doctors blamed his violent past on previously undiagnosed mental health issues.

People quoted a letter from the treating facility to the court, saying Chris needs close supervision by his doctor "to ensure his bipolar mental health condition remains stable. It is not uncommon for patients with post-traumatic stress disorder and Bipolar II to use substances to self-medicate their biochemical mood swings and trauma triggers. Our clinical team believes Mr. Brown became aggressive and acted out physically due to his untreated mental health disorder, severe sleep deprivation, inappropriate self-medicating and untreated PTSD." Serious stuff!  

Chris has been making "great strides" in rehab, the letter states, and his life is very structured — he wakes up at 5 a.m. every day and does 24 hours of community service a week, plus six to eight therapy sessions a week with his doctors "to address his bipolar diagnosis, anger management, post-traumatic stress disorder and past substance abuse."

Chris has spoken in the past about the effect it had on him to see his mother beaten by his stepfather. Back in 2006, he told MTV News it was "an influence in me about how to treat a woman." He's also talked about losing his virginity at age 8 to a girl who was 14-15.

It sounds like he has a whole team of people trying to help him identify and work through his past issues to move forward, but CNN said Chris still seemed disappointed to not be allowed to leave rehab. During his hearing on Friday, the judge said Chris still has to be tried on an assault charge in Washington, D.C., and then the judge can decide if Chris should go to jail for violating his probation in the Rihanna assault.

According to CNN, the judge will revisit Chris's rehab status (versus jail time) on April 23, which is a week after the assault trial in D.C. In the meantime, we hope CB gets all the help he needs.

What do you think of Chris's diagnosis and rehab stay? Are you hopeful for him to break the cycle of violence with this new knowledge, or do you feel ... less hopeful?
