Answering fans' questions during an interview for Google, the musician also explained that she does not feel any sense of vengeance towards those who had bullied her.
GaGa said: "I think one of the most awkward things that was ever said to me (after she became famous) was, 'Well, my my! How the tables have turned'.
"But to be honest, I don't have that kind of vengeful spirit in myself and I never did. It was just more that - and I say this with so much genuineness, from my heart - is that bullying really stays with you your whole life, and it really, really never goes away.
"I know [that] you're using words like 'superstar' and 'most Googled' and 'billions of YouTube videos', but I was never the winner. I was always the loser, and that still stays with me. And do I want to stick it anybody? No, I just want to make music."
The star added that her recent single 'Born This Way' is "a song about saying, 'This is who I am, this is who the f**k I am'", a statement which attracted cheers from the audience.
She also joked that her former classmates make plenty of requests for concert tickets.
