“Worry is the Law of Attraction working AGAINST you.” So TRUE!
“That which dominates our imaginations and our thoughts will determine our lives, and character. Therefore, it behooves us to be careful what we worship, for what we are worshipping we are becoming.” ~ attributed to Emerson, but wherever it originated, it is observably true. Worry is self-fulfilling. (My mother was also a worrier.)
You are right and I would rather suffer the slings and arrows of the real world than lose myself to the dark morass of self-doubt and worry.
That said, I have gone into that rabbit hole and struggle with the effects at times.
