@utopia, I agree with @Former-Member. They have stuffed up and you are entitled to make a formal complaint. The hospital will be obliged to buy you a new hairdryer, if they can't locate yours. That is only fair.
However, maybe use this opportunity to practice deep breathing and mindfulness. I'm sorry if it sounds like I am trying to dismiss your pain over this! That is not my intention. I only don't want to see you upset.... you deserve so much to have some peace and serenity.
You are so right- outside in the real world, things go wrong all the time. The other day I mislaid my keys and then just yesterday our land-line wasn't working at home and I couldn't make the calls that I wanted to make. Frustrations are always waiting for us!! Frustrating things happen to everyone, though. Sometimes we forget this.... mishaps, lost things, delays and misunderstandings are very common in life.
Try to think of the borrowed hairdryer that the electrician gave you as a special blessing. I know it is not easy. You would much rather have your own hairdryer, I understand. I would too.
But right now, just in the moment, accept that some things really are out of your control.... but that you will be ok.
