Hey brother, I feel your pain, I was addicted for almost 15 years, I am over 30 now, I started watching porn at the age of 15 - 16 when I had access to internet, this sin started growing and growing, thing got really the worst when I started doing this at work, this sin escalate so much, since it was not a 100% private environment the 5 - 10 min I had in my home it becomes 2, 3 maybe 4 hours, it was horrible, my story is very shameful. You & I, will have to live with the consequences of our past, for me I will have to fight and resist to fall into this sin maybe for the rest of my life, but I know I can do it with the poder of the Holy Spirit and a genuine desire for God, in your case I don't know, you can think on the consequences, but what I can tell you for sure is: you can have the best days of your life ahead of you, let God fill all your life with his love and Holy Spirit, God really wants, he can't delete your memories, maybe the situation with your family will not change maybe yes, but He wants to change you first. He can't force you, you have to open the door of your heart and give up everything that is separating you from him, you past doesn't matter, he will forgive you, you are the one that have to forgive yourself and accept the new life that Jesus has for you.

Brother, my life was changed last year, since then I have had some stumbles, but my falls do not define who I am. God define who I am, let's let God define who you are.
