My ex posted and shared in a Tiktok LIVE my intimate and nude vids and photos. I don't have screen shots. Help?

I do not have pics of it because she has me blocked, but I keep hearing people talking about such crystal-clear details that the only way to know that is to have seen it. They have also described my room, what it looks like, and my tattoos. I tried going to the sheriff, but they said if there are no pics, they can't start a case. She did it again a week later, and I am still blocked, so I can't get the evidence. I have opened a ticket with Tiktok to check lives on those dates and certain times, but I feel so lost and defeated, like I'm hitting a wall and a dead end at every turn. What can I do? PLEASE help
