I made a big mistake.

Yesterday I was on twitter at the worst time because there was a wave of accounts, likely bots, posting CP. I was in shock when I saw it but today I really started processing and I've been feeling horrible about seeing it. I also felt guilty and ashamed because I used to watch stuff that I shouldn't have on a site I found on the dark web when I was younger because I was curious about seeing stuff around my age. At the time, I didn't take into account what was really happening in the videos. I turned 18 in may and seeing this content triggered me today into going back to that dark web site that I found to prove to myself that I wasn't still aroused by what I used to watch. I want to clarify that I am still attracted to people in my age group. I did stop watching this stuff for a while. Revisiting this site did not help me, especially because I'm 18 now. I feel guilty and ashamed and have been struggling with my thoughts all day long.
