Not fitting in with family

This Christmas, me and my mom are planning to go visit our family in Virginia. I feel a little excited but at the same time I kinda hate the idea. The reason why is because I feel like I really don’t fit in with hardly anyone up there. I feel like I’m ignored and just don’t belong. I think my aunt doesn’t like me that much at all. During our last visit, my mom got mad at me for little stuff. I have a cousin who is 5 and most of the time I just don’t feel like playing with her or anything. Sometimes I feel really annoyed by her and I feel like people hate me for that. And this christmas, one of my other cousins who just got married, her husband and his parents will be coming over and what his parents do each Christmas is sing christmas carols, read parts from the bible, and sing happy birthday to the baby Jesus. No offence to any religious people on here, but I hate the idea of the Bible. And the idea of singing happy birthday to Jesus, wtf! I don’t want to be a part of that at all. And I’m happy knowing that the whole time me and my mom will stay at a hotel other than my aunt’s small trailer. Does anyone else feel this way about their family? What can I do to get over this feeling that my family up there hates me? I feel so alone there most of the time.
