Under the weather

Yesterday, I was not in a good mood. A disgusting guy said something bad about me behind my back. When I know heard what he had said, I got so angry that I wanted to fight back. His words were malicious. I really hated him! After I calmed down, I thought about what I have  had been through, and I realized that it didn't wouldn't help if I did something like what he had done. It would not make my me feeling better, but make me become an disgusting person. Maybe I should let it go. I will meet all kinds of people including good people and bad people. This is life.

Note: Instead of saying "This is life," you could also say as we do: "That's life." 

I hope you feel better. Good luck with your English studies! :)
