First i'd like to say this is going to be long, and I never post on forums so I apologize if I do it wrong but i've seen threads like this before so I thought I'd give it a shot anyway.
I live in the U.S. and im 19, i've not been able to get this out of my head for over a month. I'm scared and sick, Ive been depressed ever since it happened. That being I was browsing 4chan which I dont do often at all, in fact hardly ever. There was a post on there with an image that just had a few characters on it with text next to it saying to look those characters up on multiple search engines. I figured it was nothing and did it, using the last search engine they listed which I had never heard of before. Being compulsive and idiotic I decided to do it, what came up looked like maybe nudist photos or something else Id rather not say because it disgusts me so much. I wanted to reported whatever I was looking at but I saw no option to do so, so I just exited out after maybe a few seconds. This was on my phone so I reset it but it still haunts me. Its like PTSD, constant flashbacks of it and fear that the police are going to just come arrest me for something I didnt want to do or had any intention of doing. Ive been anxious for over a month and it just makes me so sick, and all I wish is that I could go back in time. I look at porn sometimes too and sometimes it says stuff like teen and that makes me even more worried that maybe ive seen stuff like that before and never knew it. Its all so worrying and scary. I've never been so scared in my life and I just dont know what to do. My first thought was to report the post to the police or something but im afraid Id just get in trouble for it. I dont even know if it was illegal but it looked so suspicious and gross. Help
