Here's how bad off Amanda Bynes is ... it looks like she could be in a mental health facility for a year and a half.
Amanda's lawyer was in a NYC court today ... in connection with the case where Amanda allegedly threw a bong out the window of her apartment.
Her lawyer, Gerald Shargel, asked for a postponement for up to 18 months while she got psychiatric treatment.
Sources tell TMZ ... the likelihood is ... the case will be plea bargained ... there are major weaknesses in the prosecution's case. Translation -- the case could possibly be dropped altogether.
Amanda Bynes' mom is dropping her bid to get a permanent conservatorship, but not because she's turning her back on her very ill daughter ... it's because she already has the ammo she needs to protect her.
Amanda's mom was slated to go to court Monday to make the temporary conservatorship permanent. But here's the deal. Amanda is currently on an LPS hold -- translation, doctors have a tighter rein on Amanda than her mother would have with a conservatorship.
And there's a twist. Doctors have given Amanda's mom the power to make medical and financial decisions for her daughter under the LPS hold.
The mom has already exercised her power by getting Amanda admitted long term to UCLA Medical Center.
Bottom line. There's no need for a conservatorship anymore, so she's withdrawn her petition.
And finally, and sadly, we're told there has been no real improvement in Amanda's condition."
