<human>: My dad died when I was sixteen and left me with a bipolar mother and sister. The three of us were very close until we got into a huge physical fight when I was 19 and I moved out on my own. I met a guy with a kid and fell in love with them both and have been playing house ever since.  I love it.

Well the holidays are here and I received a text from my mom this morning (8am) saying she needs to know what time I'll be over Christmas day. I have no idea.. it's two weeks away. So I tell her I'm not sure yet, but things will probably be the same as they have for the last couple years. She misunderstands my texts and starts pulling the guilt trips. "If you don't want xmas you don't have to. Just tell me what you're doing, I don't really care." and then she gets my sister in on the action and she texts me, "You're all we have. Mom just wants to spend the day with us three girls."

I'm honestly tired of her selfish bullshit. My husband has dinner at his grandma's that I don't go to because I'm always with my mom, and that side of the family thinks I hate them. He gets upset because I can't be with him on his favorite holiday. I miss him and his kid. No one is happy and I don't look forward to this day that is supposed to be a great family celebration. 

I've tried inviting her to my husbands families and she refuses. Just wants us three girls.. for the entire day. 

I want to sit in my room and watch movies and get high all day.

What should I do?
