@Roberta,
My total sympathy, Roberta. You know this visiting-the-hospital routine far too well & you know it's going to continue for quite a while yet. Yeah, it's probably mind numbing & tiring, but it's gotta be done. No choice.
I'm sorry you got your appointment day mixed up & wasted your precious time and your money. Especially when you have other important things you must do & money is short.
I so look forward to the day (and it's gonna come!

) when you are free of this necessary grind.
In the meantime, Roberta, commiserations. Hang in there.
