I think you need to get to the root of the problem in order to extinguish the behavior. Why are you acting like this and lying? To me it seems like it's stemming from insecurity about just being yourself, and wanting people to like you. The irony of that is by lying, you're going to end up with a lot of people not liking you much in the end. You've got to try to figure out who YOU are and work on developing that. People are going to like the real you a lot better than some made up version that you're presenting. What are you good at? What do you like about yourself? What have others mentioned that they like about you? What about you is unique? The answers to those questions are going to be the answer to "who are you?" That's the person you need to present to others. However, it's hard to present that person until you spend some time figuring it out for yourself.
You aren't in control at all by doing this. You're actually completely out of control because sooner or later those lies catch up to you. That's beyond your control. The only way you can control this is to try to work on finding an identity for yourself and stick to controlling that identity...not any fake ones.
