Former Nickelodeon actress Amanda Bynes is responding very well to her treatment for schizophrenia and her parents reportedly have never been happier.

"Amanda is responding very well to the medication she is taking for schizophrenia. Rick and Lynn are absolutely thrilled with the progress she has made in such a short amount of time.

"She continues to see doctors several times a week. Taking a class in fashion merchandising at a fashion school in Orange County has been an incredibly positive experience for Amanda," a source told Radar Online.

"It's only one class, but it's enough to keep Amanda busy. The only kink is the commute which from her parents house in Thousand Oaks to Orange County is long, and Amanda is always driven by one of her parents or another family member.

"When not in class or at the doctor, Amanda has been frequenting the gym. Her parent's have told friends they feel that they have their beloved daughter back for the first time in years," the source added.

Bynes was placed in an involuntary psychiatric hold after she started a fire in Thousand Oaks, California last month. Her mother, Lynn Bynes, is currently her temporary conservator.

Bynes was estranged with her parents for years and reportedly had problems with her mental health for some time now.

"Amanda has heard voices for years, and was concerned she was being spied on via smoke alarms, and clocks in her home. She would cover electronic items because Amanda believed that was the only way she wouldn't be spied on. It's extremely sad situation because Amanda just refuses to get help," a source told Radar Online.

The actress had been mired in a succession of messy controversies, starting with an arrest for criminal possession of marijuana; accusing the New York Police Department of sexual harassment; and culminating in Twitter wars with fellow celebrities.
