Dear someone who's name shall not be mentioned, Thank you

Dear someone who's name shall not be mentioned,
Thank you for making me feel like absolute crap,
Excluding me from our general group of friends,
Making me cry,
ruining my day,
treating my best friend like crap just because she wants to see me on her birthday,
and being so stuck up, you don't notice how big of a jerk you are.
sincerily,
your ex best friend,
Sarah.
