Source: Amanda Bynes suffering PTSD problems, wants to get better

Last week a California judge granted permission, at the request of doctors from the Hillman Psychiatric Center in Ventura County, to extend Amanda Bynes’s psychiatric hold for another 30 days. According to state law, such an order can only be approved if the patient is “gravely disabled as a result of a mental disorder” or “is a danger to others, or him or herself.”

But a source very close to the 27-year-old former child star tells us her prognosis is not all doom and gloom.

“Amanda has made significant improvements, she is doing better than she was,” an insider told FOX411’s Pop Tarts column. “There are no drug problems involved, it’s all mental. She has deep anger and PTSD, which tripped a psychotic episode… She is very ill, but manageable. Amanda genuinely wants to get better and has wanted to get better for some time.”

We’re told the PTSD (post-traumatic stress disorder) stems in part from the pressures of her Hollywood career, in which she shot to Nickelodeon stardom as a child, before declaring that she was “retiring” a few years ago. Bynes also has very deep-seated conflict issues with her parents, with whom we’re told she's not particularly close.

Still, Judge Reiser did grant Lynn Bynes temporary conservatorship over her daughter on Friday. But unlike the case of Britney Spears back in 2008, the conservatorship is very limited, and more of a “safety valve” to stop Bynes from making an irrational decisions.

“Amanda can’t make important decisions regarding her finances and welfare,” explained the source.”But her parents can’t either. Everything still needs to go through Amanda lawyer and the judge.”

We’re also told that Bynes agreed to stay for the extended 30 days the night before the court hearing, as her team expressed concern she may try to leave treatment sooner than what would be appropriate without the court’s involvement.

“She is easy to deal with at the moment and agreed to stay,” continued the insider. “While she is doing much better, Amanda needs to be monitored. She is on heavy anti-psychotic drugs and that requires constant medical observation. She wasn’t able to attend the hearing on Friday because at this point in treatment, she should not be moved.”

Bynes has been staying at the Ventura-based psychiatric treatment facility since July 22, where she was taken in on an involuntary hold after starting a campfire in a stranger’s driveway.

According to our source, at this stage, the conservatorship is not likely to become permanent.

“It doesn’t happen often (that it is approved) because it is a really big deal,” California lawyer Anahita Sedaghatfar added. “It is basically taking away a person’s liberties, and (Bynes’s parents) will have to show that she really can’t take care of herself.”

Lawyers for Amanda and Lynn Bynes did not respond to a request for comment.
