Demi Lovato recently opened up about how she felt after her 2011 bipolar diagnosis, sharing that it helped her get a better grasp on extreme emotions throughout her life. "I was so relieved that I had finally had a diagnosis," Demi said during the Hollywood & Mind Summit in Los Angeles, per People. "I had spent so many years struggling, and I didn't know why I was a certain way in dealing with depression at such extreme lows, when I seemingly had the world in front of me just ripe with opportunities." The 30-year-old pointed to moments that should have been a happy experience for her like being on tour as a teen. "I remember being 15 years old on a tour bus and watching fans follow my bus with posters and trying to get me to wave outside the window," Demi recalled, "and all I could do was just sit there and cry." As for why the Heart Attack singer felt it was important to go public with her diagnosis, she noted she wanted to pass on what she's learned to others in similar situations.
