Yes a second this.
I also think look back on the TDL and think about what's important, if you've managed so far without doing is it REALLY that important? What are the effects if it doesn't get done? If they are minimum- then just scrap them and move on!
Try and start afresh with a new list with less on.
I know being in a school is different from an early years setting, but please take care of yourself first 😊 You need to achieve a healthy work/life balance. You always sound very committed to your job role- but you need to put your own mental health first. Think- 'If I left my job tomorrow, would they still be able to carry on?' ...the answer will be - yes they'll carry on just fine! Bear this in mind when working on TDLs!
Learn to say 'no, I can't do that' (and don't include 'sorry' in that statement!) and Delegate when possible.
