I bought a little gadget on Amazon that tests your stress levels. Only been doing it for 4 days but every day my stress levels have been higher in the mornings 8am - 11am.
Every test I did, my stress was lower and nearly always in the good range from afternoon to bedtime nomatter how anxious I had felt in myself during that period.
In fact yesterday I was feeling ok anxious wise in the morning, yet the readings showed my stress as above average when I tested it.
Shows that stress is hiding there even on the good days.
