Visit to the heart specialist at the Hospital

I spend approximately an hour at the heart specialist at the hospital. Since then I have been carrying a mobile blood pressure measuring machine, and I feel pretty ridicules walking around with the buzzing and humming from the machine in my pocket, and the "breathing" from the thing around my arm.
It measures my blood pressure and pulse each 15 minutes, and if something seems wrong, it measures an extra time. I'm supposed to carry the equipment for 24 hours, and I have absolutely no idea of how I am supposed to fall asleep.
I haven't told the children or my mom about this, I don't want them to worry - but I miss someone to talk with. My friend and I went outside for a cigarette and talked a bit while sitting next to each other on the stairs...

That felt good and safe to be there with him, and I know, that even though I try to put this down as a little thing, that he understands, what I think, and understand my worries.
The staff is totally hysterical about me and where I am, its not really very comforting. It feels like "too much", and reminds me, that something bad can perhaps happen to me. When we came back from smoking, there had been a change in staff, and they couldn't find me. And the sight of the relieved staff, when I was back with my friend, made me feel even worse.
It's not enough that I have this damn thing twisted around me, and a wire sticking to me around my neck(?) The look of their faces, the empathy, the nursing, the little pads on the shoulder meaning "its going to be allright" - that starts to freak me out.
Well, I better find a movie to fall asleep to, if that is even possible. I think i'm looking at a long night here, unfortunately.
