Women - Confessions

I am a 20 year old girl (i'll be 21 next month) and i am a sex addict. I was molested around the age of 6 years old, and ever since then, i've been extremely sexual. I masturbate every day, and when i am home i look at porn all the time. Wanna know the very worst part about this? Something i'm not even comfortable to say on here....i am a missionary canidate, and i work for an organization that fights for women who are stuck in prostition and pornography. I am the biggest hypocrite ever. I do not struggle with homosexual feelings, but sometimes i think that if my parents were around, and if they actually loved me, then i probably wouldnt have the feelings and desires i have right now. I want so badly to live my life for Christ, but i can't seem to kick this habit. I know that when i screw up, there is grace. But i don't wanna do it anymore! All i want is to be loved, but i have to search for it myself. This is the easiest way i have found so far. I wish someone could help me. How can i stop this before this leads to something worse?
