's mother, Lynn Bynes, who was granted legal control over her daughter
, is speaking out for the first time, saying the troubled actress "will get through this situation."
"I would really like everyone out there to know that almost 99 percent of the things written about my daughter in various media outlets are false or misleading," Lynn, 66, tells PEOPLE in an exclusive statement.
"Unless it's a statement issued by our family attorney, Tamar Arminak, please take everything you read about Amanda with a grain of salt."
Bynes, 27, has been hospitalized at various facilities since a driveway-burning incident
on July 22, and was recently transferred
from UCLA Medical Center to a Malibu facility where she'll remain for the foreseeable future.
In the face of intense publicity about her daughter, her mother cautions, "Please know that neither myself or other family members have ever released any information regarding her treatment or diagnosis. We truly believe in keeping our daughter's situation private for now."
"We appreciate everyone's heartfelt support and we hope that she can get some privacy and the respect she deserves during this trying time," Lynn adds. "Both my husband and I love Amanda very much and we know that she will get through this situation."
