Reboot starting

Hi, I am 41 and I use porn since 2008. I have a problem with porn and it is many years I am aware of this. Since the beginning I had used porn for many hours a day and night. Periodically I felt the need to stop but always I get back to seek release.. cutting the story short, due to the boredom of a work that I feel not engaging me anymore, I am now seeking porn also during the working hours with a big impact on the quality of my work, my moods, self estime and quality of life. I feel lonely because I have choosen to do not share this problem with my wife nor family. I am ashemed of myself. Up to now this is not impacting my sexual activity with my wife even if I am aware of a lower excitement that I fight to not show.
every day is a battle and I need help because I have always lost up to now. Sharing on this forum I hope that could be useful in giving me the strenght to keep away from porn. I am now on day 3 and I hope to end this day without porn.
