Imagine that your best beloved will be having this operation. How might you make it wonderful for them? If they loved flowers or scents, you might arrange for those. Do they have favorite (health-promoting) foods? You’d stock up.
But it’s you, so maybe you think you only deserve top ramen and energy bars. Or maybe you’re waiting and hoping that someone else will intuit your needs. If you have a spouse or others living with you, keep in mind that they are already having to take on everything you’re offloading, so is it realistic to expect them to make it perfect for you? So quit holding that against them and organize things for yourself ahead of time so you can be comfortable.
