I have commited adultery several times in my life, at looking

I have commited adultery several times in my life, at looking and thinking lustfully on girls and women, some of them even married, and masturbated on that. I'm deeply sorry and regretful for what I've done, I'm only 13 years old, beginning on the puberty and I grew up on a family of atheists, who blinded me of God's love to me and the rest of mankind. In fact, my family blinded me so much that I even question the existence of God.
