I'm so sorry about this. No one can change what happened, but the future is in your hands. And with time, I'm sure you'll find the strength to keep living your life and finding happiness. It's not your fault, and you are not defined by what people did to you - you're the one who defines yourself! Take small steps and try to take good care of yourself. If you don't feel ready to share it with your family or friends, write about it, reach out to 7 Cups or to a therapist if you think it could help. Let things out in one form or another. Start looking at what is good and valuable about you, it can help you loving yourself more, and overcoming the idea that what happened defines you.
It's not easy to stay strong. Sometimes it even seems impossible. But it's all about small steps. Going through the day. Keep moving. Keep fighting. This way, you'll give yourself a chance! I send you all my love!
