Culinarialy - I make the same prefast meal every year. It's very simple. I saute onions, red pepper, broccoli and cubed chicken filet in a little oil with some garlic. I toss that with whole wheat spirals. It's delicious. It's meat, so it's festive, and the whole wheat and protein make the fast a little easier. And it tastes good cold so it's good for leftovers (I wouldn't reheat it.) Anyway, I haven't tossed it together but the components are cooked.
Spiritually - eh. I even gave a Shabbos Shuva drusha yesterday - the Sabbath between Rosh HaShanah and Yom Kippur, and there is always a Sabbath between them, is called Shabbos Shuva, or the Shabbos of Repentence, and it's traditional for rabbis to give a talk - a drusha - about repentence. If the rabbi is well-known, it may even be adverstised. It was my turn to give the weekly parasha class for my Shabbos afternoon women's group, and I chose to give a drusha instead. And it turns out that the ladies wanted that. In fact, the hostess told me she was hoping I'd do one. And it went over well, but it doesn't mean I'm at all ready, or have even been doing anything in that regard.
I'm just hoping to make it through the day. I'm taking V-8, crackers and my blood sugar monitor with me.
On the other hand, this is the first time I've cared that I wasn't spiritually ready, so that's a plus.
(And we never did start builiding our sukkah.)
