Chris Brown Has Been Diagnosed with a Mental Illness.

According to TMZ, Chris Brown has
been diagnosed with the mental illness
of bipolar disorder, severe insomnia and
Post Traumatic Stress Disorder ... and
that's why he has had such anger
issues ... this according to new court
docs.
Chris was in court today for a progress
hearing in the Rihanna beating case.
Documents were filed by the facility
where Chris just completed 90 days of
anger management therapy. In fact,
Chris stayed longer, just completing 95
days.
In the legal docs -- obtained by TMZ -- an
official from the rehab facility wrote
that ... in addition to his diagnosis ...
Chris was self-medicating
inappropriately.
The facility writes, "Mr. Brown became
aggressive and acted out physically due
to his untreated mental health disorder,
severe sleep deprivation, inappropriate
self-medicating and untreated PTSD."
They never explain the cause of the
PTSD. The letter also says Chris was
diagnosed with Bipolar II.
The letter says Chris is on meds for the
bipolar and other conditions.
Chris has learned various relaxation
exercises, according to the letter, and
he's tested negative for drugs, including
weed, during his stay.
The facility says he's doing really well. It
says he gets up at 5 AM and works hard.
They say he's been especially good with
community service, saying, "Mr. Brown's
attitude has been beyond exemplary in
regard to his community service
responsibilities."
