Amanda Bynes -- I'll Be Home for Christmas

Amanda Bynes will be home in her own bed by Christmas ... TMZ has learned.

Sources connected with her treatment tell TMZ ... Amanda's meds and psychological counseling have sufficiently stabilized her so her doctors will let her leave the Malibu rehab facility where she's been held since September.

As TMZ first reported ... Amanda was released from the UCLA psych ward and went to the rehab facility because the psych ward was freaking her out and preventing her from improving.

Doctors will release Amanda to her mom, who will then take her to the family house and provide supervision. The move will take place sometime next month.

We're told -- aside from the fact that the meds and therapy appear to be working -- doctors are concerned that Amanda is going stir crazy. She's not allowed to go outside because paparazzi are hanging out at the facility and the staff is worried if Amanda is around other patients and pictures are taken, it will compromise the others.

Calls to Amanda's parents' attorney, Tamar Arminak, were not returned.
