First I'd need to sort out what I fear. Is it real or something I think might maybe happen? It is our nature to worry about things that will probably never happen (invaded by Canada, inland tsunami, hit by a bus). Maybe it relieves the pressure on what we do see (friend with tumor, appliance on its last legs, family problems).
Humans are complicated. Our strength, but also our downfall. If I worried about what was real, and was happy for what I have my life would shortly sort itself out. But where is the fun in that?
