I meant to get back to you earlier, but the afternoon disappeared on me. I finally tried that route through the park, and you were right, it was much quieter than the main road.
I took the longer loop because I needed a break from sitting still, and it helped more than I expected. The air felt lighter after that brief rain, and there were hardly any people out which made it easier to think.
I kept replaying our conversation and realized I was overcomplicating something that really just needed a simple first step. I wrote down two things to handle tomorrow, and that already makes it feel less messy.
I also remembered your suggestion about bringing a notebook instead of typing everything into my phone. It does make me notice details better.
Anyway, I am glad you checked in. I am feeling steadier now, and I think a normal evening with something warm to drink and an early night will probably reset everything enough.

I was thinking about what you asked, and I do think starting smaller would make the whole thing easier. Every time I try to organize everything at once, I end up spending more energy sorting than actually doing anything useful.
What helped this week was picking one corner, finishing that, and leaving the rest alone until the next day. It sounds obvious, but it changed my mood immediately because I could see progress instead of a giant unfinished project. I even put on music and stopped timing myself, which kept me from getting annoyed halfway through.
I also took your suggestion and left my phone in another room for a while. That made a bigger difference than I expected. I was less distracted and somehow more patient.
So yes, I think your approach makes sense. I am going to keep it simple, knock out one piece at a time, and avoid turning it into something more dramatic than it needs to be.
