I need help 19f I'm not against anyone and fighting for my justice

So there is this 15 year old girl on Instagram. She took my photo from my yesterday's story , idk how she got it because I have blocked her and reposted it on her story with the caption "Rnd" . She called me a fugly b&tch with a hairy cunt and a slvt just because I told her my ex who is a friend of hers had raped me . Rape can happen to anyone and the guy doing it can also be a sweet and understanding friend. I already had a lot of shame related to the rape like I had gone to his house but changed my mind and I blamed me for it for the longest time . But after I joined feminism community, I understood what I had been through was rape. I have a very heavy heart now , it was my birthday story , someone uploaded a birthday story , my birthday was yesterday and this is what I found out today. Even my friend is confused about it and I hope she isn't too stressed , she was clearly disgusted tho. I guess my ex even showed her many things my ex is very problematic guy. Idk how to press charges on him , I'm 19 , I don't want my college or parents to find out , I were a minor when it happened and I had volunteerily gone there to his house. I mean it's probably too late to report anything. Worst of all I continued my relationship with him. Also I can't sit with this anymore because I have felt shame about it for the longest time and if complain and it backfires then my whole life is ruined . They call me his crazy ex and jealous bitch and one of the sickest parts . I don't know how to go about this , I won't end my life even if it's hard now , I'll never stop fighting for me when I'm right. And what will his mother think about me ? What if she tells her friend who is my dad's friend and he tells my dad.
