Fakeness is not being rooted in truth. Fake action is that which doesn’t come from You = Steerage = God = Truth. Instead, you act on energies that you’re convinced by and are essentially your gods. For more context on that last part, see post On Energetic Belief.
Fake action is not wrong per se. It is what it is. Most of it probably must be lived through (at least to a degree) to become conscious of its fakeness. So no judgment, just try to be honest with yourself.
The more conscious you become, the more authentic you will be. Because with rise in consciousness, energetic convictions are dispelled. So you follow less of the energies that aren’t God.
For me, the process of deconstruction of an energetic belief (= halting my conviction in the energy and seeing its fakeness) involves crying it out and a strong intention to be free of impurity. Essentially, if I want to be light, happy and a clear channel for God / Steerage / Reality, I must let go of “my wants” – which are energetic convictions in disguise. When “you” want something, it really comes from a strong belief that you want it; It’s these energies attracting you and you being convinced that they are good. But these energies aren’t likely your True Will. It’s not how Reality would unfold if you were surrendered.
Another very big part of deconstruction for me is eagerly jumping into action even if it’s fake in source. Again, most energies probably must be lived through to an extent to see through them clearly. What’s important though is reflecting on the action. Without introspection, it’s likely impossible to deconstruct an energetic conviction you have. Memories from action are your grist for the introspection mill.
It should also be said that there are gradations to fakeness. Some energies are purer, lighter and reflect truth better than others. But they still aren’t the silent truth itself. You should probably let go first of the heaviest, most draining energetic convictions imprisoning you. Then work your way up – until there’s nothing left.
