I don't keep with Kardashian stuff and hardly know who Chyna is. But I can kind of relate to this on a surface level and want to share why I think it's possible to be so emotionally upset by seeing your own nudes you mess up an important testimony. I have no idea if she's being truthful or not.

So when I was 18 and in college, I took nudes of myself and my bf at the time did as well. We even shared them on reddit for fun. He slowly became more controlling and abusive, so I left him. He didn't like that and threatened to send my nudes to my family, post them with my selfies, and was hell bent on ruining my future. I ignored him at first, but he saw me hanging out with a platonic guy friend and did in fact send the pictures to my family. My aunt sent me screenshots of the convo with him and I had a panic attack so severe, I triggered my asthma and ended up in the hospital. The university got involved and he was kicked out for revenge porn, but I was so messed up by then, I fucked up my own testimony to the conduct board, missed finals, and ended up in the mental hospital for suicide. It was a dark time. I took the pictures and let him take them of me for specific reasons. I only consented to the photography and me, myself posting them to certain subreddits anonymously. Him taking them and threatening me with them and even showing my family in an attempt to hurt me was traumatic and damaging.

Hope this helps a bit.
