So i had a fanpage, and i met this dude saying that he knows how to dox, fry, and swat and he said he was learning how to get into phones. He started talking to me a bit and he once told me "im gonna dox you." My anxiety went up and I got scared. He said he was joking. 2 days ago he got discord and someone on twitch we know got swatted. He told me "wanna be next" and I got really scared and had a really huge anxiety attack. He then later on said that he thought i knew that he was joking. I talked to my friends and they said to block him and not be worried, but im starting to worry that if he posts my address and all of that. I blocked him but im still worrying if he can still get my ip, i also deleted my fanpage and way back he said he can still dox even if the user is deleting. What should I do?
