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" charted within the top 20 in the Czech Republic, Denmark, Italy, the Netherlands, and Spain.

Andy Gill of The Independent wrote that this song is connected to Anastacia's battle with cancer :"It's more likely to be the trigger behind the anthemic positivism of 'Welcome to My Truth.'"

In the music video, a young girl is seen watching her parents having a fight, while clips are shown of Anastacia in a garden singing that "she has hit about a million walls".

The father – played by actor Wade Williams – reluctantly leaves the house and waves goodbye to the little girl.
