"Welcome to My Truth" is a song by American recording artist Anastacia from her third studio album, Anastacia. Written by Anastacia, Kara DioGuardi, and John Shanks and released as the album's third single in Europe on November 8, 2004, the song chronicles Anastacia's strained relationship with her father, who left her at a young age, along with the singer's battle with breast cancer. While "Welcome to My Truth" failed to match overall the success of its predecessors, "Left Outside Alone" and "Sick and Tired", it fared relatively well in certain European nations, such as Italy, the Netherlands, and Spain.
