I am sorry that the world is full of people who do these kinds of things. I’m sorry that you are suffering. I recommend that you tell a trusted adult or friend. Someone who you trust and know that they will not go and tell anyone else unless you grant them permission. I understand the fears that you have however, if you can, work yourself up to telling your mom. As a mother, all she wants is for you to be safe. It is your choice if you want to press charges or not, but she may urge you to do so. The boys that did this, if not met with some sort of retribution for their actions will continue to do so. Who knows how many others they have raped and how many more they will rape. I strongly encourage pressing charges, however only if you feel comfortable about it. Please talk with someone tho. A trusted friend, or an advisor. A family member, a doctor. If you have any pets, this may seem silly, but you could tell them as well. I wish you luck, and hope that you can have peace of mind soon.
