I don’t want to live this way

For a long time I’ve used porn as an escape from my problems. I started at an age younger than I want to admit and I’ve used it almost every day since then. It’s ruined relationships and made me a person I don’t want to be. I started to realise this about 2 months ago and tried to quit. Every day I think about relapsing and the urge just becomes too much to bear. How can I stop for good?
