How to get revenge on a friend who betrayed me?

Asked by Dunkeepcalm (28) January 4th, 2013 from iPhone

We had been best friends for two years and she was cool. It was always great to have her around. Then one day she just started hanging out with two other girls and always laughed with them for nonsense things that I don’t really find funny. Sometimes I feel like she also has forgotten about me so I was very moody. I hate her for that. Then suddenly, she just told me that she thinks we shouldn’t be friends anymore. So…yeah. For that I really really really hate her and want to get revenge on her but I have no idea how to do it. Please help people! And I know most of you will just say make new friends but that is impossible because everyone already has besties so there is nowhere for me to fit in. ( BTW guys, I’m still in primary school so no stupid ideas )Please help! :(
