I'm probably quite lucky: I never felt any real shame at using porn, only for wasting my time. And now, in hindsight, realising the harm it has done. But not the crippling self-loathing that many here seem sadly to have got themselves into, sometimes through religious guilt, or having damaged their relationships or in this case (the OP) repeatedly failing to give up and relapsing. So I liked this answer, which seems to me to point to the solution. Forget the self-loathing, inward focus, and instead just stop. Throw the devices away if they're the trigger/cause. Find something else to do. But just stop. And think about something else. Don't over-complicate it, and don't feel shame. Just stop.
