Moore was immediately admitted to the hospital, and now is thought to be in a treatment program at Cirque Lodge in Utah.
"Of course the situation weighs heavily on me," Rumer told Germany's tz-online during a trip to Berlin for a Thomas Sabo jewelry event over the weekend.
"My mother is on the road to recovery," she added. "It's slow going but we believe in her."
Moore's recovery isn't the only personal issue on Rumer's mind. While she was in Germany her Hollywood home was broken into. Currently under construction, no one was in the building at the time, but after cutting through the gate with a blow torch or something similar the thieves made off with over $10,000 worth of power tools.
In addition to rehab, Moore is said to have reached out to old friend and spiritual advisor Deepak Chopra to aid her in her recovery.
