I was reading your post and it reminded me of myself because I know how it feels man. I would experience the same: I see something triggering. Then maybe a day or two later I see something else and it feels like I’m constantly dancing on a thin line between relapsing and keeping the streak.
What I find useful in these situations is to make it clear that watching those scenes or doing google “research” is not safe for you and this needs to be handled properly. Maybe start looking at the triggers more closely using a “Trigger-Thought-Action” log (apparently I have recommended this one already):
So long story short, increase awareness and create space between you and the thoughts. You can take ownership of you reaction.
