Could I?

There were so many things had happened in these few days.
I'm feeling so down for work now. I am so sad.

I don't really understand why people love to talk bad things behind others back.
I don't really understand why there are so backstabbers at my workplace. :(
I hate them but I've told myself not to hate people who did something bad to me.
So what should I do? TELL ME!!!!!!! :'(
Can I just forgive them?

I really hope I could.
