Tillich called the mind "a permanent factory of fears."
It keeps dressing formless dread as a fear of something, because a named fear is survivable and dread is not. So your worries can be decoys: you fix one, another takes its place.
But the dread underneath isn't a flaw to fix. It's the cost of being finite. You were never meant to delete it, only to carry it.
So what if the goal isn't a life without the fear, but the strength to hold it?
