Stoic Practice Opportunity

I am applying for a visa to such-and-such a country. In order to get the visa, I need a criminal background check. The first one I applied for was deficient. The second one I applied for was deficient and the government contractor was too rule-bound to fix it. I set up an appointment to get fingerprinted tomorrow--for the third time!--and just now, when I logged into the system to confirm for myself my appointment, it's telling me that there is no such appointment or application number. Unbelievable. 

I guess this is a Stoic practice opportunity.  

I want to put it out of my mind while I try to sleep here. There's absolutely nothing I can do it about it now until they're open to receive phone calls tomorrow at eight a.m. Any worrying I do between now and then--either consciously or at some lower brain level--will be useless.
