Me again....

I know this isn't serious but I am filled with angst all the same. I have only just found out I have a six month check up with the respirologist to discuss the use of my cpap machine (breathing masks used for sleep apnea) next week. I just know he will chastise me as I have barely used it at all. I am supposed to be aiming for sleeping a full 6hrs minimum with the mask on but I manage 3hrs tops. I have tried - truly I have tried. I wake up after 2-3hrs with this alien on my face, panic and struggle to rip it off. It takes 15min to calm down and realise it was only the mask. It is truly a terrifying event I go through every night.
