How can I deal with my family?

I came to visit family for 2 months to work and hang out. It is my last week right now and the whole thing has turned to family feud. My grandma apparently forces me to do things I don t want to do. She doesn t. Some of my other cousins hate her. Then it turns out that my uncle might be narcissistic and is manipulating people into hating my grandma. I got in an awful situation today. I feel terrible and I don t know whose side to go on. I almost just want to jump off a bridge or something. I cant stand this feeling. My younger cousin gives me lectures on how I shouldn t listen to my grandma. I tell him to treat her with some damn respect. He is a brat. He never has to do anything. He dropped out of elementary school because he wanted to be homeschooled. He is lazy and he gets whatever he wants. He doesn t even have to clear his own plate. I think hes cool and all but he is not respectful and is never made to do anything. My uncle also backs him up. My cousin never gets in trouble. He played a prank on his other grandma that involved a mug filled with water that he somehow put upside down on the counter. Then she picked it up and got covered in water. He didn t get in trouble at all. I hate this family conflict. I want to go somewhere else right now. I cant stay in this family battlefield. I also don t want to go home because I am not always getting along with my parents and I am starting school. I just want to get so ****** up drunk right now
