There are a few things to be done about fear, to be free of it or mitigate it.
You can take the precepts and hold them, reflect on that, " I harm no one, no one has reason to harm me because I am harmless".
You can give priority to something more important than yourself, like in the Bodhisattva Vehicle.
You can enter concentration systematically checking,.. "With what does stress, annoyance, fear, pain come?" Then suspending that process or view until the view of self, even motivations, is suspended.
These are things that work to free us from fear. I've tried them all and they work, maybe someone will remember and apply these things.
