Please Mormons only, I'm addicted to masterbating, what should I do?

I'm a 14 year old boy and 2 and a half years ago I started viewing porn and masterbaiting, since then I have been sealed to my family, I'm really scared to tell my bishop or parents about my problem, I feel really ashamed of myself and I really want to go on a mission and live with the savior again it's just that I'm so scared, I need help, what should I do? Will I have to get sealed again? P.S. Please only Mormons, I don't want to hear anything from anybody that this is natural or that I need to leave the church, I love the church and masterbaiting is a sin.
