Okay, that would do. "Погружённый в ложь (not во лжи), я не могу жить в мире с собой".
But you might take a shot with another one though: “Запутавшись во лжи, не в силах больше быть в мире с самим собой”.
The first phrase relates the feeling of hopelessness of your ever getting out of that puddle of lies you were thrown into against your will. You are stuck in there unable to free yourself. Not a perfect motto to live by. While in the second one you’ve been searching your way probing here and there for the right path, but sh**t happens, you took the wrong turn, you made a mistake, you got entangled in lies, you have gotten fed up with all this and you are ready to break free.
Yes, definitely the second one, as is, no changes allowed any more.![]()
