Selena Gomez is doing well after her two-week stint in rehab last month, and thanked fans for their support.
"I've done everything I could to the best of my ability," Gomez wrote on Instagram Feb. 10. "Thank you for the unconditional love and cyber hugs. You inspire me."
On Feb. 5, Selena revealed that she had checked into a rehab facility for undisclosed health problems. Gomez was treated at Dawn at the Meadows facility in Arizona, a center that treats 18- to 26-year-olds for substance dependence and mental-health issues.
Selena's reps denied the singer was treated for alcohol or drug addiction, but numerous reports claimed the brunette beauty had developed a dependence on alcohol, weed and had suffered an emotional breakdown after her break-up from Justin Bieber.
In December 2013, Gomez abruptly canceled the Asian and Australian legs of her tour. In a statement, she said she needed to take care of herself, but did not elaborate further.
"It has become clear to me and those close to me that after many years putting my work first, I need to spend some time on myself in order to be the best person I can be," she said.
Selena, 21, was diagnosed with lupus several years ago. Lupus is a mysterious autoimmune disease where the body's immune system attacks normal, healthy tissue.
Symptoms include joint pain, facial swelling, fatigue, inflammation and headaches. It's unclear what exactly causes lupus, and there is no cure, but eating well and getting lots of rest is crucial.
