I'm so glad that you're going through things from psychology - it's really, really tough to do that and I'm so proud you are. Definitely signal the end and then get up and do something completely different. Can you plan something good for you for after?
Well done for the self care of going back to bed.
One step at a time, you're doing brilliantly.
Stella - haven't heard of that app, but that's a great idea.
