I think society lies to itself all the time - the problem is no only yours. In the end it is your choice - even if you feel you developed a habit of lying. You can take time, every day or every week or every once in a while, to site alone. Where you can isolate yourself from everything else. You can try to write your thoughts down. Then read them. Then listen to your feelings closely. For it is not in your mind but in your heart - that you know better - if its a lie or truth.

You can also do this:
Write down a few subjects you suspect to be lying about on pieces paper, fold them and throw them in a way you don`t see what you wrote. Then you pick up one and read it. Then try to see if this is not the most lied about, or one of the main reasons.
