How to stop being cowardly

Hello everyone, this might be a strange question but it's something that has been plaguing me for the past few months.

I've been doing a lot of personal workings for the things I want. And I have been asking the Gods a lot throughout the process for help, signs and guidance. And certainly they have given it. And yet because of the nature of what I have been working on and how much it affects me emotionally due to its personal importance I constantly doubt and ask for reassurance from the Gods. And they have given me signs that is impossible for me to doubt at times as well. Yet I still am afraid that I am wrong. Afraid that I am actually deluding myself due to bias. Afraid that how I interpreted the signs was wrong.

There are moments where I am calm. I think rationally. And everything is okay. Then in the next moment I am doubtful and afraid. And I go back and forth. Praise the Gods for having the patience for dealing with my mental and emotional chaos.

So the question I have is, how do I stop doubting and being afraid. To have the courage to believe in myself and the Gods even when things are a mess internally. I have never doubted my faith in the Gods. I am who I am today because of their teachings and I have no question that things would be so much worse without their guidance. But things have been such a mess inside even though outside there truly isn't anything wrong.
