a medical question

Just how connected are my heart and my hands?  Because my hands have been cold all this week.  Numb fingers, crying out for pockets to hibernate in.  My heart feels achingly similar.  Some sub-zero cloud of concern and fear has hunkered down around my core.  I feel worried about all things career and financial.  Weirdly this comes just as I’ve experienced a remarkably fruitful few months.  Worrying does me no good at all, I realize.  I need to generate my own high pressure system, blow this cold dark funk out of here.
