I'm regretting joining art class.....and i love art

I am proud of who I am. I am a pansexual with a beautiful girlfriend who I love and cherish. Lately I've been going to class with my pride lanyard on and getting hate from the Freshman. Today one of them used a very derogatory term I find extremely rude and disrespectful. Not to mention it shouldn't be used in a school environment. And this Freshman had the indecency to say it to her friend who sits right next to me. While I was there. She told her friend "God doesn't accept gays" and "God she's a f****t" She wouldn't say it to my face but made it loud enough so I could hear her. I'm feeling really down and want to just disappear. I am proud of who I am but if I react to her words I'll get in trouble for it. she won't listen to a teacher, or any voice of reason. No instead she continues to bully me because I'm not like her. She's making art class a living hell.
