If you're afraid, you are grossly uncertain. As uncertainty increases, fear increases.
And yet at the same time, as you become more uncertain, you become more certain that things are uncertain. Uncertainty becomes real. And if uncertainty is real, you definitely are justified in being afraid.
So whatever fear you're having, it's because you're uncertain about something and have moved into the ego. The ego is not certain of anything. Uncertainty can't be the truth, which means fear can't be the truth.
Reclaiming a sense of certainty, confidence, clarity, surety, automatically alleviates fear. But you must become confident about what is really true (God's truth) rather than confident about the ego's truth.
When you are afraid, you are confident that you are in danger. Its a strange thing, to be sure that real certainty is threatened, or to be sure that invulnerability is threatened.
Truth is, you can't be sure that uncertainty is the truth. You think you can, and while you're in uncertainty you'll keep looking for a sense of certainty. But you're already certain, just about the wrong thing. It's a bit of a mind-bender, but to get out of fear you need to be less certain that uncertain things are the truth.
What CAN you be truly certain of? This takes some honesty. Are you absolutely SUUUUUURE, like, really really really sure, that outcomes are terrible, or that people are plotting against you, or that you aren't safe? Are you REAEAAAAALLY sure about that?
If you test that, in the extreme, and if you demand total honesty from yourself, you have to admit to yourself - no, you're not sure. There's so much uncertainty that you do not really FEEL sure even if you're certain about being uncertain, lol You tend to feel what the surface appearance tells you, so if you're sure about uncertain things, you'll FEEL uncertain. But if you're sure about certain things, you'll FEEL certain.
The only thing you can be certain of and feel sure of and re-assured by, is God's love and God's truth. Ego's truth will never reassure you. Be more certain that God's truth is true and ego's truth is false. You are not in danger. You are safe in love. You can be sure of that.
