Being a diabetic, I wake up with a low blood sugar.  Immediate panic! Am I late for work? What time is it?
I come to find my phone, and realize I'm not late.  Then walk out to take my dog out, and the security lights for my apartment building are out. Pitch black. Shadows that seemed to appear from nowhere raised my anxiety, just a little higher. I'm at work now,  and anxiety levels are coming down.
