Bynes, 28, thought that though working as a bartender would be hard because of the attention she gets owing to her celebrity status, it would help her get back to normalcy, reported TMZ.
Bynes spent five months in a treatment facility in July 2013 when she was placed under involuntary psychiatric hold.
She was released in December and appeared to be getting her life back on track until a conservatorship giving her mother control of her affairs came to an end last month.
