The singer explained that the 14-minute clip for her new single 'Marry The Night' is about the day she was dropped from her first label Island Def Jam.
GaGa told E! News: "It was one of the worst days of my life and it happened quite quickly, but in my mind, when I think back on that period of my life, it all happened very slow. It is my personal way of seeing things.
"If you give up after something like that, you were never destined to be an entertainer."
She added: "I love obstacles. To marry your obstacles mean I, the artist, wholeheartedly accept everything you throw at me. I am destined to struggle, I am destined to write music about the struggle, and I accept it willingly."
X Factor USA judge and former Island Def Jam boss LA Reid recently admitted that he dropped Lady GaGa from the label after hearing a few of her unfinished demos while he was having a "bad day".
'Marry The Night' is the fifth single to be lifted from GaGa's second album Born This Way and is available to download now.
