I'm thinking of cheating, lying and stealing something.
Why do you want to cheat, lie and steal something?
I think it would make me feel better if I did these acts.
I know you think you would feel better if you were to lie, cheat and steal something, but these actions are unethical. You should think about why you want to do these actions and how negative the consequences are. Think of other activities that would improve your mood and make you feel better.
I just don't want to get caught.
You should stop this right now. You will only hurt yourself in the long run doing this.
