I'm not making this post for sympathy I'm posting it because I'm lost and I really need to vent I dont know what to do I'm only 17 and I feel like I've already ruined my life left my moms to live with my grandmother because my mom is addicted to heroin I've been with at least over 20 men since I was 14 mostly because I'm insecure and gullible and believe what people tell me I've been raped twice used, abused by boyfriends I just dont know what I've done so wrong for all these things to happen to me I'm ONLY 17 I feel like I've completely messed up my life and my name 🤦🏼
