I'm planning to place a plastic bag over her head and suffocating her.
You're gonna commit murder? Why?
She was fucking up my life
That doesn't mean you need to kill her. If someone is disrupting your life, remove them and get on with your life. Revenge is never worth it.
I'm definitely doing it without killing her. I just want to make her suffer.
You know what you're thinking of doing is a serious crime. Please calm down and rethink your actions.
