So far I've been able to handle emergencies well enough. The longest lasting situation was last July.
I received a call from my stepmother that my dad was very ill, and she needed someone to go and look after their horses and such.
Two days later, I was on a plane with my daughter and cat, and ended up staying at the farm for a month.
My dad died, and then my stepmother flipped out at me about something very small, but I found I was able to handle the high stress and looking after six horses pretty well, but I know that after more than a month, I would start going to pieces and making bad mistakes. I was starting to get into the inability when my stepmother kept piling more and more on my shoulders, then got angry when I couldn't follow through.
It was a huge responsibility looking after these horses, and my stepmother said I did really well for the whole month she was away with my dad at the hospital, but that's what fools people into thinking I'm actually normal, and then they can't understand why suddenly one day I cannot function. They must think people on the spectrum are either unable to do anything at all, or they can do things when they want to.
Strangely enough, I can deal with all sorts of difficulties-- except when it comes to dealing with people. When others freak out, I get rattled.
There's nothing I can do about it, either. So, I've accepted my limitations. It's just that other people couldn't accept them...
