In terms of what's happening to you at school; that is bullying. Please know that you have an absolute right to feel safe at your school and that no one ever has the right to bully or abuse you in anyway.
There are a few ways that you can deal with bullying in your school. The first is to talk to an adult at school, either a principal, guidance counselor or school administator. If you're not comfortable doing that; try talking to your parents and then they can talk to the school. It is the school's job to make sure you are not being harassed or bullied.
In some schools there are groups and organizations that support LGBT(Lesbian, Gay, Bisexual, or Transgender) students. Doesn't mean to say that you are; but that they help students by making sure they are safe from such behavior.
You are just starting your life; you have so much to look forward to, high school, college, growing up, getting a job, marrying; and having your own kids some day. Times may look dark now; but there is a light at the end of the tunnel and you will make it through. You are strong and brave and incredible. Don't let bullies tell you otherwise.
