This whole saga is sounding very Britney Spears-esque!

Even before Amanda Bynes' latest arrest in N.Y.C. last night, her parents Rick and Lynn were concerned enough about their daughter's erratic behavior to consult with lawyers about obtaining a conservatorship, Radar reports.

"Rick & Lynn have met with several lawyers that handle conservatorships in the past month, because they want to get a conservatorship over their daughter. They have been advised that even as disturbing as Amanda's behavior is, it's very unlikely that a judge would sign off on a temporary conservatorship," a source dishes.

The troubled actress is so unpredictable that she even reportedly called 911 on herself the night of her marijuana bust!

"She called 911, saying the cops were going to assault her," In Touch sources claim.

Her parents want to get her the help she desperately needs, but it looks like they might not have the best of luck!

"Conservatorships are very hard to get, and being mentally ill and addicted to drugs isn't enough. Amanda hasn't ever been to rehab or ever agreed to see a mental health professional. Her parents are absolutely powerless to do anything at this point," a source adds.

We feel for them!
