I think I might just have to take my feelings into my own hands
How will you take your feelings into your own hands?
I'm going to beat her up.
It is okay to feel angry and upset but you should be careful about how you handle your feelings. It is good to seek help in finding healthy ways to manage your feelings.
Beating her up is how I'll manage my feelings.
That's not managing your feelings at all. You are taking out your anger on someone and they will call the police. Then you will have to face those consequences.
