I appreciate everybody's help and advice, truly. I feel safe going to bed now. Nothing's changed, especially, nothing's gotten worse. I'm breathing fine, both through my nose and my mouth. I'm carrying the cordless phone and the cell phone with me whenever I move out of this chair. I know with 100% certainty that if I did need to call 911, the fire department has access to a key that not only lets them into the building but also into the individual apartments, and that the station is only 1/4 mile from here; the police station is a half mile away, and as I said, the city's ambulance service is across the street.
My alarm is set for 7 AM, the doctor's office opens at 8, I just need to hit redial, plus it's programmed into my cell phone. I WILL be calling as soon as the office opens, even if I feel better!!!!!!!!
