The Highs to the Lows

Not only did I wake up this morning and it was hot again, but also my oxygen concentrator is on the fritz and I have to send it to a repair shop in Tennessee.  I know this of course because I needed it.  Fortunately, it concentrated oxygen just fine for me, but it has a problem detecting my breathing, and it beeped at me constantly, which was not conducive to sleeping or reading, or thinking about anything.  So I have to arrange temporary oxygen now, for while it's gone.
