On Ellen DeGeneres' chat show, Lovato spoke about her struggles and how she felt abandoned by her people several times, reports femalefirst.co.uk.

"My core issues are abandonment as a child from my birth father. He was an addict, alcoholic. We had to leave him and I had vivid memories of him leaving. It played on that fear and I felt abandoned so I drank. That night I went to a party, there was other stuff there and it was only three months before I ended up in the hospital with an over dose," she shared.
