Her car flew off the track during a race earlier this month, catapulting spectacularly over safety barriers before hurtling backwards into a hut housing media and officials.
The 17-year-old underwent marathon surgery when doctors battled for more than nine hours to repair her fractured vertebra and remove a bone splinter, which was sitting dangerously close to her spinal cord.
Despite her ordeal, Floersch has said she is determined to race again.
"Today I am flying back home. Really happy to see all my family and friends in the next days again," she wrote in a Facebook post Monday, after spending more than a week in a Macau hospital.
"I am still overwhelmed by all the support I got from you fans all around the world," she added.
Doctors at the S. Januario hospital in Macau said that while it may take months for Floersch to make a full recovery, she has already made significant improvement, and expect that she will eventually be able to return to racing.
"It was my first ever big crash, and it took me some while to get over it, but I am over it now, but I think now a new chapter starts", said Floersch at the press conference. She also said that she expected to come back and race again next year.
