Or **"stabilizing"** - hinting the improvement of a depressive phase. Nothing is felt if no phase was active or no change occurred. - -**This is no treatment plan - just a starting point for your own research efforts.** - -When you end a sitting, check that the LED of the Arduino is still on and _not_ blinking.
