I'm thinking of shoplifting. My life felt empty so I started shoplifting. Is this going to end well?
Oh wow, are you kidding me or not? Why did you think of stealing things? Why did you start doing that?
Hurting myself on purpose is a way of me being in control of my life.
It sounds like you need therapy for this. Shoplifting is wrong and will only get you into a lot of legal trouble. Try to get therapy if you can.
So I should ignore all my emotions?
You shouldn't ignore your emotions, you should get mental help for them though. Stealing anything is going to look bad on your personal record and you'll have difficult times finding a job. Be more motivated to look out for yourself more.
