Lying tends to come from fear and lack of trust.
What are you afraid of that prompts the lies?
You need to look at why and see how you can deal with the issues that make you fearful/ untrusting/insecure, and how to be more honest/authentic.
Fearful lying can become an automatic habit, one that needs to be broken progressively.
How to be ‘you’ in a charitable sincere way?
if nothing seems to help or work, i think this should be a last resort, one ought to be motivated by love and not fear. i would recommend you think about hell, each time your about to sin, think about the consequence, know that God is watching you, and that sin might be the sin that takes you to hell.
