Stressed: not eating, restless (very active), getting sick.
Happy: eating & shedding well, keeping regular hours (resting-lying low by day, & in ambush mode at night), no signs of health issues.
Snakes are happier when they're hiding, & feeling secure (snug in "hides" & relaxed when held close to us) as opposed to a panicky (very active) snake when held.
