How can i handle all this alone?

Hi. A few days ago my dad asked my sister, me, and my mom if we wanted to go visit our relatives in mexico. I made the biggest mistake in my llife by saying yes. So my dad bought the plane tickets and we flew to mexico. after 2 days my evil aunt called to say she was also visiting and when i heard i almost dropped dead. i do not like her because she always tries to get into problems with my mom for the most stupid reasons. one time she made a huge rumor that me and my cousin we kicking her 4 year old in the balls and i have no idea whyshe made the rumor because theres no point in kicking a small child in the balls and i sure wouldnt. Then about 3 days later and my mom started acting up. She asked me to go put on a belt so i went to go get it and when i tugged on the little handle thing it snapped and broke. I tried fixing and my mom said to hurry up because she was going to the ice cream shop. i failed at fixing it and i dont know why but she came and got the belt and striked me across the face and now i have a line across my face. the next day i was eating steak with all the family members. i got up to get a piece of steak and my mom saidto not be such a pig and get a small piece. the piece i got was as big as a 5 year olds hand. and i answered yes mom but i had no idea why and she got up and slapped in the mouth and my mouth started bleeding. i asked what was that for and she said i answered disrepectfully. do you think Yes Mom is disrepectfull? i dont. then i went in my room to rinse my mouth. the next morning i got up and heard my grandma and my aunts saying that i was the most disrespectull grandchild. i always answer politley and always mind my manners and now there saying im disrespectfull! I dont say bad words or get in fights like my other cousins.. My cousins call me the white boy because im not as crazy and ill minded as them and i tell them to stop being racist and that theres nothing wrong with being white. tonight im going to call my dad to get me a plane ticket back. but im sure my dad will say to wait 2 weeks before he can do it. what can i do in the mean time to prevent all this? im sick and tired of it :( thanks for reading
