I’m scared

Ok so I’ve been on pornhub for a while and when I click on a video it goes to a other tab and the other tab says someone knows my IP address and I didn’t think anything of it until today it said that I got hacked and like in two minutes the hacker will release all the photos of my face and stuff. I put a sticky note on my front camera, prayed (even though I’m not religious at all) and I’m terrified of what could happen. Has anything like this happened to someone and if so could stuff like this could happen? I’m truly afraid and shaking on like people releasing any information of mine and my world will come crashing down.
