I know it is stupid but...

So I've been trying to get ahead of myself with all the things that leaving a house, a town and a country require.
Flights, end of tenancy notice, shipping companies, cancelling this, cancelling that, arranging to get rid of various items, sell others, have a good holiday on the way...
Last week I completed several of these tasks and was at the point where basically only the holiday bit (and the actual packing) still remained to be done.
Then today, I find that one of the bits that I had thought sorted several weeks ago (cancelling gym membership) wasn't. I found this out because they took more money off us. But only my money. They have managed to cancel Husbink's membership, just not mine.
It is not a big deal. At worst it means I get to use the gym for another two weeks. At best it means that when I get to talk to the right person tomorrow, they realise their mistake, give me my money back and on we trot.
But it has really wound me up. One of those silly, silly moments when you feel "if this has gone wrong, what other bogey men are waiting round the corner to stuff up my plans!?" Rational, I know.
I'm utterly capable of this feeling in reverse too. If something that I expect to be difficult goes well then suddenly it feels like everything will run smoothly, there will be no glitches, all will, indeed, be well.
It appears I am not capable of taking each event on its own and simply dealing with it. This caused me endless problems in probability classes at school and uni as I refused to accept that the next outcome was not influenced by the former (I'm not talking about just rolling a die here - though I can put forward a good argument for that not being a series of independent events too).
Husbink and I were playing cribbage earlier and he had won each round and was very close to winning the game. Very close. I said I thought it pointless to continue as there was no way I was going to win. Of course, it was possible for me to win still but based on the previous rounds, unlikely. My mood, the shuffling of the cards, etc, etc, all combine at this point, in my mind to make it far more likely that Husbink will continue to win. He views the events as distinct.
So just because I lost at cribbage and the gym have briefly been useless, does not mean that we are going to get booted out of our house a week too early, arrive at the airport to discover ALL FLIGHTS EVER have been cancelled or that our shipping will end up at the bottom of the sea somewhere but just now it sure as anything feels like it.
