Demi Lovato appeared on MSNBC Live With Tamron Hall on Monday to discuss her work with the national initiative Be Vocal: Speak Up For Mental Health. She also spoke about her own struggles with bipolar disorder. As the spokesperson for the cause, Demi is making an urgent plea to lawmakers on Capitol Hill for better mental health treatment in the US this week, especially as it relates to gun purchases. The 23-year-old singer and actress spoke to Tamron about her own journey, saying she thinks it's important to remember that people with mental illness are more likely to inflict harm on themselves and become the victim--rather than be the perpetrators.
