My ex was abusive

My ex physically and emotionally abused me, for well over a year. One day I broke down when I was with my friends and told them everything. I’d never told anyone. I got the confidence to leave him, I stupidly had this image in my head of everyone believing me and realising how awful he was. I felt like no one really believed me because from the outside, we looked so perfect. I got viewed as a ‘psycho’ and it broke me. I’ve moved on and this was a few years ago now. I guess I just need to vent. I want to scream it from the rooftops how awful he is. I want to post it online, the pictures of the bruises, the voice recordings where he laughs as he strangles me. I know it’s a stupid idea but I still feel angry about what he did to me. Therapy isn’t really available here before someone suggests that. Can anyone relate?
