Hello Spotted Giraffe,
Its very nice to meet you, I don't think I've seen you on the boards before.
This definitely a very hurtful situation you are dealing with. And it definitely does matter, your feelings and concerns matter a great deal. You are very brave for coming here and posting about this. Your concern shows what a good and caring person you are.
I'm not sure but you seem kind of young, and you are all the more brave for coming forward.
Is there someone you can talk to about this, somebody at school perhaps, an adult you can trust? I think the first thing to do is to find out where you can get help. Perhaps the local children's aid society or social services can help of you feel safe contacting them.
RAINN has a hotline you can call anonymously to talk to someone that maybe able to point in the direction for getting help in your area. The number is 1-800-656-HOPE. Here is a link to their website RAINN
The most important thing is that you get somebody to talk to and stay safe. Please do, and thanks again for posting it was a very brave thing to do.
