porn addiction and masterbation

i've been trying to stop but i can't, there are times i realize i have a problem, there are times i go to help websites, i know i'm not strong enough alone, i realize and have called out to God for help, but i continue to slip back and disobey, its not enough to confess and ask for help, i'm so tired of this life, i'm 3 years married but it does not help, i'm just tired and need to grow up.
