Am I addicted?

I’ve been watching porn since I was 10, on and off, sometimes more frequently, some periods not at all. It all started with some vague SE and my curiosity wanting to know more. It then kind of stuck as the best way to relax/ distract and a way to fulfill my urges. Sometimes I don’t watch it for a while, other times I watch it very heavily. Sometimes I don’t have a problem with it, but other times (like right now) I get really ashamed, embarrassed and upset about it. Also I’m afraid to approach girls, so this is my safe way of doing it. I just feel like I depend on it too much.
