Amanda is suffering from a severe mental illness

Remember the girl that said she wanted Drake to murder her vajayjay? yea, Amanda Bynes, well it turns out she's suffering from a SEVERE mental illness "with schizophrenic tendencies"

 The struggling starlet was under observation all day yesterday, and Doctors allegedly already determined that she's suffering from a SEVERE mental illness "with schizophrenic tendencies"!!!

Apparently Amanda was lucid for about 10 hours yesterday, during which she was calm and sweet, but after that her personality took a turn for the worse! According to reports, she got totes frustrated and even "shut down."

At one point, she allegedly was so out of control that she needed to be physically restrained!!! They even separated her from her roommate because she was insulting her so badly!

So far, drug tests have apparently come back negative for everything but marijuana!

Schizophrenia is a brain disorder that affects the way a person acts, thinks, and sees the world. People with schizophrenia have an altered perception of reality, often a significant loss of contact with reality. They may see or hear things that don’t exist, speak in strange or confusing ways, believe that others are trying to harm them, or feel like they’re being constantly watched.
