She was on her worst behaviour, word to Drizzy, and now doctors know why. Amanda Bynes has officially been diagnosed with schizophrenia and bipolar disorder. “She does indeed have schizophrenia and bipolar disorder,” source close to her family confirmed. “It was what Amanda’s parents, Rick and Lynn, had suspected all along. Nevertheless, it was difficult to process for Amanda’s parents. The bright side is that Amanda can lead a long, normal life, as long as she takes her medication. Doctors at the treatment facility are still working to get Amanda therapeutic meds and she’s responding to the medications she is being given to treat her dual diagnosis.” So glad to hear she’s going to be okay!
