It was clear long before people saw Amanda Bynes doing drugs and driving around aimlessly this week that she has been on a disturbing downward spiral.
Friends say she is "not in touch with reality" ... gee, ya think?
The star is accused of two separate hit-and-run accidents and was arrested April 6 for a DUI after sideswiping a police car. Her license has been suspended.
Still, she shows no signs of slowing down, and has rejected any overtures to get help. In fact, she seems to be partying and crashing harder than ever.
"Amanda is refusing to go to rehab or seek any form of psychiatric treatment or diagnosis, because it's clear something is up with her," a close pal said.
"She has been told by her agent and her dad Rick that she has substance abuse issues and needs to get help. She's a lost little girl right now."
"Amanda's completely gone off the grid. She won't speak with her manager, her agent, her publicist; she's not returning anybody's phone calls."
"She's obviously crying out for help, but isn't ready to receive it. She seems to be having some serious mental health issues and she's always out of it."
Here's hoping she gets help for them before it's too late.
