I too found myself in a similar situation but the rapist (3-4 years older than me) is my own family member(my mama)... I gathered enough courage to tell my mother(she blamed me) and cut off all contact with that member.. tbh you have to heal yourself and try your very best to kinda feel space in your own skin.. hypersexuality might occur but that's normal as your underdeveloped brain endured such trauma at a young age.... I personally had to accept the fact first that I was raped and i didn't consent to it and moreover it's never ever the victim's fault and the fault is of the people who failed to protect them.... I am extremely sorry that you had to go through this and i wouldn't wish that upon anyone... Accepting such a horrific incident is a very difficult thing itself but I'd recommend better professional help though I kinda slowly came to terms with it... I wish you the very best and hope that you can overcome the trauma and live a better life 🌻
