trauma related to blackmail

i have been blackmailed by an exboyfriend , even though it was my fault to trust someone like him ( he had personal photos of mine) he abused me he threatened me to make those photos all over the internet . i was in my period while he was asking . he didn't care and asks for more *** in specific way while i was naked and no pad on me .. my period blood was all over the room i can't breathe since then .. everything was just a nightmare i can't imagine what i did. i want help but no one is helping, family and friends can't know , my region is strict. i am not good at all .. i was brave to tell the police but i am so weak to express my feelings to others irl .. i hate that room .. i search the social media million times a day just to know if sth published by him or not.
