I dont belong here...

I have been working here almost 5 months but I still can't get along with my own collegue. Sometimes, the way they talk very sarcastic. I know maybe its my fault I forget to tell her to return call her boss. I didn't mean it. Takkan about that pun until now masih sakit hati. I hate working here. Until now I still feel like I'm a stranger here. They all are so pathetic! I hate them! I don't want to work here already..O God please help me. I just wish there is another open job for me. I feel like I don't belong to this company. I can't stand here anymore. :-(
