Two things which I have found effective are mindfulness and action. These two things are useful in different contexts of feeling fear. I find mindfulness to be useful with big picture types of fear, the sort of stuff you lay awake in bed late at night thinking about. Climate change, fascism, existential dread. It’s far easier said than done, but practicing being in the present moment instead of dwelling on things in the future and past which are largely out of your control is incredibly valuable and something I think everyone should do. And it is a skill, practicing it will make you better at it. Meditation is very useful for this. Action on the other hand is something I find more useful for specific fear, fear caused by a particular event, situation, thing, etc. Think public speaking, introducing yourself to someone, standing up for yourself, etc. Once again this is a lot easier said than done, but you kinda have to just do it. Like mindfulness this is a skill that also gets easier with practice. A phrase which I have found really helpful (shoutout to Dave from Shoeless in South Dakota) is “you don’t think your way into acting differently, you act your way into thinking differently”. I find that if I wait to feel like doing something I’m afraid of, I’ll never feel like doing it, but if I simply do it, I’ll realize that I had nothing to fear, or if I did, then it’s something I can handle. This makes sense in a way. We know as materialists that ideas don’t shape and change history, material things and actions do. Why would it be any different on a personal level?

I hope this was a bit helpful and that you can conquer your fears soon. Also don’t ever blame yourself. I think self compassion and acceptance that you’ll fail sometimes is incredibly important in the whole process of facing fear and anxiety as well. Like lots of other things, this is something meditation has helped me with too. Good luck comrade
