@CalmAmethystLapwing3067 - Some people do experience anxiety associated with using CPAP. What follows is what I advised my CPAP patients in the sleep lab, and especially the last few lines are so important. Understanding the physiology of your upper airway without AND with CPAP is imperative, and relaxation is key.
"“Take some big, deep breaths, completely relax.
Put the mask on your face as you turn the CPAP unit on…
Relax…Close your eyes, clear mind of all thoughts...
Keep lips closed, but don’t tense lips….
Let pressure fill the back of your throat…
IMAGINE your upper airway
being kept open by the pressure…
Breathe with it, not against it………
Breathe slowly…Concentrate…Now, Relax...”
