Not feeling well and don’t know what to do with the starter

I made my starter last night and was busy all morning and didn’t get a chance to make my dough yet. I follow my dad’s recipe - stretch and fold every 45 min 4 times. After that meant to let it sit for minimum 6 hours before shaping and leaving it in the fridge overnight. My problem is that I need to have it ready to bake tomorrow before 3 pm (I keep Shabbat) and I’m not feeling very well I’m very dizzy and in bed but I can probably get up to do some of the steps. Anyway my question is with all these steps which can I leave out that doesn’t make me stay up all night and I will have it ready in time. I’m on pacific time. Thank you 🙏
