I just wanted to follow up because I had been meaning to answer you sooner, and the week kind of ran away from me.
I did end up trying that new routine we talked about, and it helped me feel more organized without being too strict about it.
The biggest change was simply doing one small thing at the same time every day, because that made the rest of the day feel easier to handle.
I also stopped overthinking whether I was doing it perfectly, which probably made the biggest difference.
If you are still deciding what to do, I would honestly keep it simple and give it a few days before changing anything. That usually tells me more than reading ten opinions at once.
I am around later this week if you want to compare notes, because I would like to hear how your version works out.

I saw your note earlier and meant to answer before the afternoon got busy, so I am sending this now while I finally have a quiet minute.
What worked for me was leaving some space in the plan instead of filling every hour, because that unexpectedly made everything easier to keep up with.
I used to stack too many tasks together, and then one delay would throw off the entire day.
Lately I have been trying a slower start, a short list, and one fixed break, and that seems far more realistic.
I also noticed I am better at finishing things when I put the hardest one first and stop moving it around.
If you want, send me what you are thinking and I can tell you which part seems practical. I do better when ideas are concrete, and I am happy to help you trim it down into something that feels manageable.
