I feel complicated about my feelings towards my friends. Although i feel disgust about her, but don't know why i feel angry when she asked me about whether my best friend will go out with me or not on Sunday (30th of Nov). She want somebody to accompany her during her lunch break, but definitely not me. All she cares about is my best friend. They always SMS each other and told each jokes and special news. This made me feel like I'm a toad that live in a well. Everything they said i can't get it.
