It doesn't matter if it's at 4PM & it's 9AM now.
I can't do "productive" things.
I can't even do FUN things.
It doesn't matter if I set alarms to remind me to get ready for the thing so I COULD have lots of time in theory to rest or do other stuff without worrying.
That's not how executive dysfunction works.
And if by some magic I manage to get myself productive during this dead time, I will then hyper-fixate and forget about the appointment.
It also hits me if I’m just responsible for watching my kids that day. The simple fact that I am the one to pay attention to them will keep me from even being able to think about work. Even if they’re off watching TV and completely disengaged from me.
