 and ask for Dave. Hi, I'm Demi Lovato. I've always dreamt of using my voice to make a difference. What I didn't expect was that mental illness would get in my way. Living with bipolar disorder, there were so many times that I felt like I was alone. The hardest part was dealing with my bipolar depression. I finally hit rock bottom and decided to get help. Then slowly, things started to change. For me, it takes speaking up, finding the right treatment plan, taking care of myself, and getting back to what I love.
