This is exactly me.
I found out my boyfriend had been watching GoT (with his mum) and I completely lost it. It wasn't just the fact he did it, it was the fact he'd watched at least 5 seasons and all the while led me to believe he wasn't watching anything like that. I found out by pure chance and the shock of it meant I cried on and off for the whole day, in front of him. I cried for so long that he eventually got angry at me for crying.
This was the one thing I knew and he knew would take me over the edge if he watched it. So I felt deeply betrayed.
I tried to break up with him and then had an even bigger panic attack and tried to resolve the situation. I woke up this morning and the first thought was of him watching that and the pain it makes me feel, so I woke up and started crying.
I stopped watching shows/films that contained nudity years ago and I don't know if that's actually helping me.
I have a milder case of what's considered a breast deformity, so beyond the abuse I suffered, I'm incredibly insecure. I'm the most insecure person I've ever met. I have to stop myself from cutting my breasts. I despise them. The hilarious thing is my reaction to nudity would reduce to almost nothing if I had fake boobs, but being able to afford that would take years and this trigger is ruining my life right now.
Sorry I can't help. But I feel slightly more normal knowing other people suffer from this trigger too.
