I don’t think the worry can be lumped into four categories like that. What worries me most is when there are things going on around me that I can’t change or do anything about. When there are things happening that I can’t do anything to help or fix. This could include all four of those things you mentioned.
It varies. Currently, I am most worried that Bush will use military force against Iran before leaving office, leaving a new President and us to cope with what could literally be the “fallout” from that decision.
I’m currently most worried about money, cause I am young healthy and in a great realtionship but just bought a house, which is the cause of my money worries.
