Being alone gives me low blood pressure?

Damn - H is in Florida because of our family tragedy, but I'm not going to write about that (you know why).  This is very selfish of me - but I'm going to whine about how my schedule is off because I'm alone...
         In a way it feels like I have extra time - and I took on some big projects to keep myself busy. 
At night, though, I postpone getting into bed.  For the past two nights, I've have the radio archives of This American Life on, and I sort old papers -  There's nobody to tell me to come to bed.  Since I'm alone, when I finally get to bed I do two things designed to perturb my sleep even more:
(1) I let our two cats get in bed with me.  They have fleas right now, and I'm allergic to a lot of things.  I know it's bad and I keep them out of our room (door closed) till I'm ready for bed - still I don't want to sleep alone : ( 
(2) Then I put something on the "tv" (streaming netflix) and I fall asleep even later than I would have.

       Of course, the inevitable.  This morning, I realized it was 7:22 am and I jumped out of bed, ran downstairs to wake L, opened his door, threw him a shirt and said, "Get up.  It's 7:20!"  I closed his door quickly, but still added loudly, "L--, are you getting up?"  (My stern voice... which no longer has much of an effect).   Right away, I also threw some pizza bits in the toaster over to pack his lunch.
        That's when it happened.  A wave of  -  -  -  it.  I know the feeling, but I can't describe it.
I remember it from my surgery... hmmm... Was it my C-section?  Probably, because I was awake.  After I got the anesthesia, my blood pressure went down.  It's like you feel nausea from every part of your body, almost pins and needles, but not quite. 
        Anyway, not pleasant.
        That's what I felt about 2 minutes after JUMPING out of bed and running downstairs.
        Yuck.
Here's the good part, from my perspective.   I shut up; it nipped in the bud any potential harping at L.  He knew what I had said at 7:20, and my reminders would probably just darken his mood.  So, here's the funny part: I'm kind of grateful.  I want these constant lessons/reminders.
