Sexual abuse trigger just venting

My mom and i never had a great relationship. And when i was 16 it really went downhill. I hit depression bad. Due to remembering things from my childhood that occured 2 years - 7 years old. I was crying for help telling my mom i need to see someone i needed medication that i cry so much i didnt shower i felt like i was going crazy. I tell her what my great uncle did to me and her response was "I Knew it." So the time i remember at 3/4 years old and hes forcing me to give oral under a blanket either late at night or early morning my mom walks to the living room he starts to tickle me and says were playing. I peaked from under the blanket and my mom turns away goes to her room and goes to sleep. Thank you mom for saving me The same day I decided to tell my mom what had happened to me. My half brother comes to my room him 21 myself 16 he cries begs for forgiveness for what he did to me when we slept over at my grandmas house. I was so confused then he says you really dont remember. Then out of no where i remembered me 7 years old. Him 12 years old on top of me both naked i remember trying to push him off telling him to stop and him putting his hand over my mouth and i blacked out. Then i remember me covering myself with the blankets naked and see my 12 year old brother and 9 year old brother arguing my 9 year old brother saying what did you do shes our sister and him crying.. I remember how close me and him were and i said its okay dont cry i wont say anything. And then next morning wiping myself wondering why there was no blood. Why would I a 7 year old think that? Did i bleed before? What else happened to me?. Doesn't stop there my step grandpa at 13 years old i was sleeping on the floor in my grandparents room i went through a phase where i was scared to sleep alone in my room. My grandma left ti work at 3am and i remember feeling some thing touching me in my private and something next to me i wake up and its my grandpa laying next to me naked. I got up so fast and ran to my room and put a chair against the door knob because i didnt have a lock. Amd he chased after me to my room he couldn't get in and i ran to my batheoom where i locked myself in scared thinking he would come get me i didnt sleep all night. Amd i had to go to school the next day like nothing happened why? Because everyone in the family praises him that hes a great husband father and grandpa. I was getting bad grades and hanging with the "wrong crowd" so whos going to believe me ? Til this day i still feel uncomfortable when he hugs me. Im saying all this because I am 26 weeks pregnant with my first and shes a baby girl which im so happy about. My husband side of family yes of course usual nosy and drama but none of this abuse. My family does know about pregnancy but as im getting closer all i can think is i want to cut all my side of family off. Great Uncle is deported for molesting his step daughters never saw him since. Older brother is states away at school still comes to family occasions which i stopped attending to not see his face. My grandpa will always be around. What my mom recently told me after i said i dont trust my unborn baby at my grandmas care She says you just need to get over it. lol im not putting my daughter thru all this abuse or let her be around those people hearing their names. My mom still talks about my older brother saying oh i talked to him yesterday like why would you mention him she brings him up like if nothing happened. My mom has been trying to win me over buying me gifts etc she lives out of state visits twice a year and its better now that shes away but she thinks ahea going to move back and be allowed to babysit. Im sorry after all that happened to me and my owm mother not defending me yes ive told her this but i know if i don't want my child around that i have to cut off my grandma who raised me doesnt know any of this and she was the only mom i had since i lived with her since i was 7-13. I honestly here to vent please no judgement
