Well nigh everything, unfortunately. I am one of those perpetual worry warts...sometimes I can't even pinpoint what exactly I'm worried about, but I'm in a fretful state for whatever reason...
I am hoping age has something to do with it, or at least this phase of my life...wish I could do something other than take anti-anxiety meds but that may be my future...
Anyhow, listening to the nightly news doesn't help. After a recent newscast, I am now worried about bedbugs in hotel rooms! Apparently it's an epidemic...
