Recounting my COCSA experience (tw: details of sexual abuse, incest)

I was seven. It was my cousin who's one year older than me. My mother had invited his family over for dinner on Easter. It happened when we were playing alone after lunch. He introduced into our game of play pretend the notion that we were lovers. I didn't play pretend lovers, it has never crossed my mind to do so with anyone let alone my cousin. But I couldn't fathom something twisted beyond regular childhood foolishness being proposed by another kid, and to my child mind play pretend was all fake so I conceived of it as an innocent game. He then started giving me instructions. To remove my underwear. To lie a certain way on the floor. Spread my legs. Let me stress that I was ignorant of even the existence of sex, as well as in an environment where I felt safe -at home playing with my cousin in a culture that overwhelmingly promotes the exact opposite of weariness towards family-. I was utterly unsuspecting. I complied. By the way he was telling me to do things, it was obvious that he was fully aware of my clueless status. He expected it. Further than expecting, he clearly counted on it to be unopposed. He chose to keep me in the dark about what he intended to do to my body, inside of my body, until he just did it. He took out his penis through a gaping hole in his pants I hadn't noticed prior and penetrated my vagina before leaning on me to put his tongue into my mouth. I didn't know what any of this was. I didn't even register the latter act as kissing. My conception of kisses were pecks or smacks, which I've only ever given on my parents' cheeks. I hope that my insistence on my little girl mindset does not annoy you, it's just really important to me that whoever reads this understands how oblivious I genuinely was. I still thought we were just playing, so I rationalized it as innocent physical contact. I mimicked his tongue coiling against mine. He posed those actions in the game as proofs of love. I am convinced that he knew what he was doing. A kid truly mistaking sex for child play would have tried to approach the act with their peer on a somewhat equal footing on account of the heavy physical involvement, not the opposite by relying on the imbalance in their knowledge to get their way. His motivation was not to play with me, it was to use my body for sexual gratification and the game was just his angle to make that happen with me malleable. He manipulated me and abused my innocence. No matter how he first came into contact with sex, he demonstrated a vile entitlement to my body. The timeline of the assault is unclear in my memory. I remember him doing it twice that afternoon. I remember the housekeeper walking in on it and singling me out. She yelled my name and said she would tell my mother. I remember anguishing, fearing I did something wrong, feeling so confused and ashamed. I remember watching him and his family leave the house as I hesitated to say something (I don't think the housekeeper immediately went to my mother or maybe she was occupied). I kept my mouth shut in that moment, but after they were gone I sought my mother. I told her what he did. I was lost, plainly distraught, not far from sobbing my words out. My sister of twelve was in the room as well. She practically laughed at what I said and my mother exclaimed in shock and disgust. "How could you let yourself be fondled by your brother?!" (in my culture it's common to refer to cousins as siblings even if we really were not close). She continued to scold me. "Do you know what it's called, what you did?! It's called "incest"!" (I was so out of it, for multiple years after that I thought sex in general was called incest). "You know you could be pregnant right now?!" (that is how I learned where babies come from, also I'm still puzzled as to why she said that to me at seven). I was thoroughly mortified, panicked. I felt abhorrent and filthy. Her reaction impressed upon me that I was no victim, but an accomplice to abomination. Just as guilty as my cousin for letting him touch me. Her reprimands sealed self-loathing into my core. "Do not do that ever again or I'll tell your father!", and then it was never spoken of again. I suspect she didn't even tell my uncle or aunt about the incident, since while berating me she talked as if me keeping quiet when they were still there closed that door for good. One thing is for sure: he was never held accountable for what he did to me. He walked away scot-free and years later, my mother would sing his praises saying that God expressed to her that he has his hand on him and sermon me for not being warm towards him as he smirked at me in the spot where he raped me. Honestly, I think my mother and sister forgot this ever happened. The luxury of forgetting. Meanwhile, the memory and guilt of that day have been festering in my mind. I was brought up in thick purity culture, I'll let you imagine what kind of torment that sparked for the incestuous child sexual deviant I came to identify as. I've spent hours pouring over my sinful actions, crying, begging God for forgiveness. I lived in fear of my friends learning of what I've done and despising me. I even felt grateful my mother didn't disown me. Then I was hit at fourteen or so with the realization that I couldn't possibly have consented. And it did not relieve me. It dawned on me that I was raped, that my mother blamed me for it, that my sister (which I did love at the time, not anymore for various reasons) mocked me in my most vulnerable moment and my father served as a threat (rightfully so, he victim blamed me on several other non sexual occasions). I was terrified of opening up to anyone else lest I get another version of my mother's reaction. I was alone. This is the first time I share this ever since it happened. Along with my epiphany, a voice took shape in my head. It says that I'm worthless ooze in denial, that my mother spoke truth and I'm rejecting it. I began constantly obsessing over my rape. Dissecting it, reliving it in order to debate the voice plaguing me. Ignoring it does not work: I get anxious whenever I try to. When I do, it's like conceding the voice's affirmations which gives rise to a sense of precariousness and impending collapse in my interior world. The voice never lets up, springs out of contexts that aren't even related to my rape, yanks my thoughts towards there. I incessantly spiral in revolting places grappling with it, I'm psychologically and emotionally drained. I am unsafe in my own mind, awake or in slumber thanks to the frequent nightmares around my trauma I started having about when I turned eighteen. I just feel so intrinsically gross and fucked up. I am angry. I am sad. All the time. This condition has only worsened over the years, trampled my ability to do what brings me joy (learning, being a friend) and I don't reckon I have much fuel left to push through. I wrote all this so that my experience would not exist solely in my head, if that makes sense. If someone read me up to this point, I thank you kindly for your time.
