Can we really overcome porn adiction?

Is it really possible to overcome pornography addiction? I feel like it's so hard, it's such a powerful drug. I get desperate not knowing how to quit, I keep relapsing. I feel like it's taking over my life. Between this and video games, I feel like my life is stagnant. I'm 35 years old and I know people my age or even younger who have already achieved many goals that I dream of achieving. How can I get out of this hole?
