I'm going to make my friends feel uncomfortable
Why would you make your friends uncomfortable?
I want to hurt them and get back at them because they hurt me.
That's terrible that they did that to you.  But, you shouldn't want to make them feel bad just because they made you feel bad.  That's not how friends should treat eachother!
I don't care. If they can't handle it.
I feel like getting back at them is just going to cause more problems. You ought to sit down and just tell them that they made you upset.
