Om Swami
What should I do when I feel too afraid to take an action?
Gather your inner strength
When an action makes you nervous, and you think you cannot do it, that it is beyond you, or you look for reasons not to do it, gather your inner strength fully. Without that, it is not possible to move the action forward.
At that moment you will have to gather your inner strength fully; only then will you be able to carry any action forward, otherwise it is simply not possible.
