Women - Confessions

I've had off and on problems with lust (thoughts and masturbation) for years, but it's been intensifying dramatically lately. It's as if I CANNOT say no... at all. I feel powerless. I broke down last night, and prayed so very hard that God would give me the strength that I'm lacking, to overcome this. It's not what I want. I'm re-dedicating my life to Jesus, and this is act and these thoughts are not of God. I absolutely rebuke these thoughts, but I ask for fellow believers prayers that when the thoughts arise, God would give me the strength and heart of dedication to stop. Thanks!!!
