Fear, doubt and disbelief are not your friend - they'll retard the flow, leading to a lesser reality. But you can't simply override them with some false positivity. That bubble is sure to burst aswell. Instead contemplate the worst possible outcome which is invoking the fear. Then work into the tightness. What is it you think you need from the situation? The One in you needs nothing. Unravel it, let go of the tightness, then unleash a streaming flow of lightness through the situation. There will always be a way.
