I think life is more difficult for some people, in the way that you describe, and, for a certain group, that is because of their autism.
For instance, on my brother's last two holidays, the first one, he found £1,300 had gone from his bank account, and, on the second holiday, one flight cost £200 too much and the other was overcharged by £350. He was in the zone and panicking for two hours, but then let the resolution process, and the bank action, take its course, and chilled down and became resigned. My ex-husband, who I'm sure is somewhat autistic ( Asperger's), would have made a real mountain out of this and would have become really upset and unable to focus on anything else..
I don't know if I'm autistic, but not diagnosed, but certainly a bit dyspraxic, I think and seem to do one thing well at a time. One thing I do to reduce stress, which my ex doesn't do, is always check I have my phone and my wallet and my key. I'm prepared to double-check the detail. My ex is always leaving his phone or bank cards somewhere, and just stuffs them in his jacket pocket, unable to step up the checking.
I would, additionally, if I went on holiday, be prepared to go through a company which does all the planning and booking. I dedicate time to trying to make sure admin and practical things don't go wrong; sleep early; get up and write work reports early and have a hierarchy of priorities which I addressed in order and don't overstretch myself. That way, I don't get stressed and life is manageable.
I hope you find a coping strategy to reduce your stress too.
