I'm alone on christmas eve
Why are you going to be alone for Christmas?
I don't really like Christmas because when I was child, my parents divorced.
If you prefer to spend the holidays alone then it's fine to feel that way. I think I would be too lonely.
Loneliness is a bit of a strange emotion. That being said, I don't  feel lonely during the holidays.
I am glad that you don't feel lonely and it is okay to be alone if you want to be. You shouldn't force yourself to be with other people if it will make you unhappy.
