I'm going to confront my friend about the state of our friendship
Is there a reason you want to do this?
I'm bored. To be honest I'm fed up with your bullshit.
You really seem to be upset. It is not a good idea to be confrontational with a friend. They are sure to react in kind.
I'm full of rage. Once you feel my pain you will realize that I'm justified in taking this action.
If you are angry one of the worst things you can do is to try and take revenge. If you have problems you should talk to them first, you could do something you regret.
