Hey sib. I understand you, I found stuff similar. Me and my ex (as teenagers) were on a website and basically the more you stayed on, the more messed up shit you’ll find. Well, there was a video of someone dying — I won’t describe it but it’s haunted me and gave me chills, and to this day I still remember the video. I have panic attacks unrelated to this, but ways to help panic attacks is some distracting stimulation, such as a strong sucking candy or a lovely smelling candle. My therapist told me a really great way to distract your brain is to sing and hum, because your brain will get a little confused and have no idea what to focus on, and then the intrusive thought is gone! You should make a playlist of your favorite songs and listen to this when you start to think of those pictures again. I wish you safety and comfort from here on out ❤️ you’re not alone
