Mandy Moore has revealed she suffers from depression despite always coming across as a positive person. The 22 year old revealed she often felt really low after her break up with Zach Braff and tennis player Andy Roddick. The singer told Jane Magazine she always tries to remain positive and upbeat, however minor setbacks can often hit her harder than she expects. Moore started out as a teen singer and later crossed into the big screen, starring in films such as A Walk to Remember and American Dreamz. She says she feels bad people wasted money on her music, even describing it as ‘blah’.
