How are you feeling right now?
Had a really intense day at work. Not sure how to process it all.
Echo
That sounds like a lot. Was it a specific moment, or more of a pressure that built throughout the day?
Definitely building pressure. By 3pm I just felt completely overwhelmed.
Echo · Pattern detected
I've noticed you mention overwhelm around mid-afternoon in a few entries now. Have you thought about what shifts around that time?
