The difference is whether you’re existing in the grip of that fear or thriving from a place of love.
You could try reading something like “The Mastery of Love” by Don Miguel Ruiz to get a taste, but the healing has to come through the body and nervous system. You can’t will your way through this.
Edit: Important note: The right antidepressant can help!
Everyone’s journey is different, but depending on where that fear is coming from, I could imagine drastically different next steps.
Personally, therapy has helped me immensely. A lot of my early anxiety about these things stemmed from severe imposter syndrome, and through the years I’ve gained enough confidence in myself to know that my skills are in demand, and survival is likely in the current market.
But if that fear is due to other things - the health of your employer’s business, etc. then a very different course of action might be required.
