Tor Browsing

el
So me and few friends thought it would be funny to go on Tor the browser and dive into the "deep web" and we were looking at stuff that Ye we shouldn't have like the drugs websites and weapons websites. It was just jokes nothing disturbing or unnerving. But I was scrolling through Hidden Wiki and I clicked on a link. The worst I expected to see was child porn or something and we agreed that if we saw anything like that we would close it. But I clicked on the link and it took me to a website selling body parts. It was so grafic and i sat for about 5 mins just staring before I did anything. I am on ft to them now and they are talking but I haven't said anything for 20 minutes. I am shaking and i want to cry and throw up. I don't know how to erase my memory 😔
