Advice please: Cognitive distortion preventing me from accomplishing anything

The cognitive distortion is called “catastrophizing”, I think.

I’m afraid of unexpected, strongly negative events occurring to me without warning. Nothing specific, just a generalized fear. That fear is crippling me. Worse, there’s a part of me that feels that fear is keeping me safe. “If I let go of that fear,” it goes, “I would start doing things and then I wouldn’t be safe any more.”

I haven’t filled out a job application in over a week, because doing so would force me out into the world if i got an interview, and into the world consistently if I got the job.
