What do I do??????????????

My parents are just @ss holes! So basically I have been bullyed like crazy this year. I'm in 8th grade and the ids just kept saying horrible things behind my backbasicallyy where I can hear. some even said stuff to my face. So my parents told me "Just finish out the year and co-exist and then when you graduate you will never have to see them again" because where all going to different high schools. So this is the last weak of school and this one kid that I hate the most in the class was having a pool party and he had to invite the hole class. So now my parents are making me go and they feal bad not going because of how nice the parents are. I even said how uncomfortable I would feal and how much they have tortured me. But my dad is a maniac and is now downstairs screaming this "WE ARE GOING TO THIS PARTY WEETHER YOU LIKE IT OR NOT!!!!!! YOU KNOW THIS IS WHY HES LIKE THIS WE SPOIL HIM TOO MUCH!!!!!!!! i DONT ASK FOR MUCH JUST TO GO TO THIS ONE PARTY!!!" and I swear didn'tnt say anything bad all I said was that I do not get along with these kids and if we can please not go and my dad just freaked out. Is there anything I can do? Because they are going to just make fun of me there and bully me. Please help!
