I can't stop myself from lying
Do you say mean things to people too?
I say some mean things sometimes, but I try not to.
It is good that you try not to be mean but lying to others is not good. They will feel betrayed and want nothing to do with you.
It's fine, as long as they want nothing to do with me, but I can't give up telling lies.
You are in charge of how you live your life no matter if you think you can stop lying or not. Take responsibility for the things you say or one day people will stop believing you all together.
