The 48-year-old singer posted a smiling photo of herself on Instagram on Saturday, thanking everyone and encouraging them to stay positive.
"I've been hard at work, feeling inspired by each of your stories and uplifted by your overwhelming support," Carey wrote on Instagram on Sunday. "Let's continue to encourage each other on our journeys."
Carey revealed last week that she was diagnosed in 2001 with bipolar disorder, a condition with "moods cycling between high and low over time." Her specific condition, though, bipolar II, lacks the extreme highs associated with other forms of bipolar disorder, leaving the sufferer prone to depression. She noted that she is taking medication for the condition, which has helped her.
