Christmas in my family

[Haunted]

Lately I've been asking my friends how they spend Christmas.
My best friend said:
'This year, my aunts, uncles and cousins will come to my house and we'll spend the whole day together'
My classmate said:
'well, we spend the day with our closest relatives, like my dad's sisters and brothers. Only with them, because only couting my father's family and us we are almost 20 people in one house!"
My other classmate said:
'I don't really know, but I suppose we'll spend it with my family and closest relatives. And me and my mom are going to buy Christmas presents next Friday!"

I was just wondering...
it's been 3 years since I last spent Christmas with my family!
EXPLANATION:
This is my Christmas: my mom does the Christmas shopping all by herself or with my father. On Christmas day, in the morning, my sister opens her presents and we record the moment. Then we go to my aunt and uncle's house (which is next to mine) and we stay there. While we're there, I get bored, my sister begs to go home to play with her new toys, my mom tells my sister that we'll go home in a minute and my father usually argues with my aunt about something irrilevant. Then we go back home.

To me, Christmas is only another boring day, just a little happier in the morning.
I don't want to feel that way anymore. I want Christmas to be special and... loving. I want to feel the beauty of living in a united family at least once a year.
When I was a child I used to be the happiest kid alive because I received a lot of presents and I used to spend Christmas with my grandparents, aunt, cousins and even my great grandma, but when I turned 12 it all disappeared and I bet this year it will be one of the worst ever.

This year has been the most difficult ever and I want to feel completely free at least on Christmas day. I want to feel loved.
I don't want to hear the usual arguments between my mom/dad and me. I don't want to hear my grandma say I let her down because I don't believe in god. I don't want to hear my sister say she hates to be celiac. I don't want to hear my aunt say she's upset because of her ex-husband. And I don't want to trap myself into my room and bleed to be loved.

I just want a normal Christmas, spent with a normal family and a normal day for once. I just want normality.

Let's come to the point, I needed to vent.

What can I do to have a normal, happy Christmas with my family?
