How do I connect with others who have gone through this?

First of all, even when it feels like you are, you are never alone – Christ is always with you. He promises to never leave or forsake you. Next, find a counselor to talk with, preferably one who is familiar with sex/porn addiction. Use the internet to find one (Conquerors through Christ has a list of trusted counselors.) Find a supportive group in which to participate, such as COSA, Heart to Heart Partners, or even ALANON. Groups like these help you understand that you are not alone in the struggle of living with an addict.
