My sister has been a... well... b_tch lately toward everyone, especially me. She feels entitled. Everything has to be her way and she "deserves" everything she wants. And it's her birthday today and she wants to go out to an expensive restaurant that has items that have lots of calories. It's like... pure fat. And while I'm not overweight, I have high cholesterol (familial hypocholesterolemia) and don't want to make things worse. I also prefer not to eat fatty things in general.

Instead of deciding to go, I decided to lie by saying I'm "sick"... I also didn't get her any gifts because I'm sick of her b_tchy behavior.

I remember about 2 weeks ago when I told my mom I wanted to go to an Indian restaurant to eat dinner together. My sister FLIPPED OUT. "OH MY GOD. ARE YOU F_CKING SERIOUS???? IT'S MY BIRTHDAY THAT DAY!!!!!" She basically started throwing a hissy fit. I said, "Chill. We'd be going 1 week before your birthday. Calm down." Then she pretended like nothing happened. "Oh, I was just kidding."

Am I being too harsh? Be honest. She's so triggering sometimes.
