We're looking to locate your package

I meant to reply sooner, but the week ran away from me and I only just had a quiet minute to think it through.
If it were me, I would keep the plan simple and not overcomplicate the schedule. Start with one task you can finish quickly, then let that momentum carry the rest of the afternoon.
I usually make a short list on scrap paper because anything longer turns into a chore by itself. A quick reset helps too, even if it is only stepping outside for a few minutes and getting some air.
I have found that people respond better when the note is direct and warm instead of polished to death. It feels more honest that way, and honestly that is usually enough.
Also, I would not worry about getting every detail perfect right away. Getting something started is often the only hard part, and then the rest becomes easier once you can see it on the page.
Let me know what you decide, because I am curious how it turns out and happy to help again.

I think the easiest answer is to keep tomorrow lighter than you planned and give yourself more room between things.
Whenever I stack too much into one day, even simple errands start feeling oddly dramatic, and then I waste energy trying to recover the mood instead of just doing the task.
I would probably start with the one stop that opens earliest, then leave the middle of the day flexible in case something takes longer than expected. That little bit of buffer changes everything for me.
If you are still deciding whether to make the call, I would do it early and get it out of the way. The anticipation is usually more annoying than the actual conversation.
I also think it helps to bring something small you enjoy, like a notebook or podcast, just so the day feels less mechanical. Tiny comforts matter more than people admit.
Anyway, that is how I would handle it, but you know your rhythm better than anyone, so trust your read on it.
