My friend decided to give me an intervention and so I don't think I'll ever speak with her again.
You're that mad at her? What would you say to her if you did decide to talk to her?
I would ask her why the hell she would give me such an intervention.
It is reasonable for friends to be worried about you if they think you are behaving in a destructive way. Perhaps you should try to see things from her perspective and think about why she would have felt the need to stage and intervention for you.
The hell you're going to talk, I'm not giving a shit. She knows that I don't give a fuck.
It seems like she cared for you and thought that you needed an intervention, and even though you disagree, you can't disagree that she cares, right? Why would you want to lose someone from your life who wants you to always be happy?
