I'm going to cut my brothers out of my life
Why do you want to cut them out of your life?
I can't stand them honey. They are so good at everything
You shouldn't cut your brothers out for petty reasons. If you feel they are better at everything then this has more to do with your own insecurity.
It's not a petty reason. I hate them.
Siblings can go through things sometimes but cutting them out of your life is too much. You could miss out on having them in your life later.
