I have been on an organisation kick for the last week or so and it has helped me feel so much better. Just wanted to share as I'm sure some people here will relate.
I've cleaned up my digital files and organised them. I've got some funky themes and colour coding of digital folders on the go because computers are just so aesthetically grim - turns out there are dozens of college students on YouTube who will show you how to make your computer desktop pretty.

I've started a bullet journal - not particularly pretty but what I need. I still use my digital calendar for the source but then can take from that to get a weekly / monthly overview, etc.
I've rationalised my task list and my reference/idea files to be treated differently, so I'm not swimming drowning in a sea of ' x needs new tights' alongside 'maybe paint the dining room this colour one day'.
I've started going through some paper files although that feels less urgent as it isn't too badly organised.
Have got more motivation to tackle things like a kitchen drawer or a cupboard instead of just being overwhelmed. Feeling more in control and ready for the new term. .
