Congrats, looks like your post turned into a "big thing" :)
I do tend to worry since I'm a thinker and I think a lot about a lot of things. But I think the biological reason that worrying evolved was to move us to action. We have to realize that if there is no action we can take to mitigate the worry's cause, or we decide not to take any action after a cost/benefit analysis, then we can decide the worrying is not doing what it was meant to do, and we can move on with our lives.
Maybe, maybe not. I'm not a psychologist. Just being "part of the conversation"
Have a nice day!
