humans are warm-blooded creatures; unlike reptiles which are reliant on
ambient energy for their heat, people produce their own. i'm quite familiar
with having a chilled to the bones experience(s), and i think it may indicate
a need to fire up the internal furnace.
it could be that you're an empath, and that you've strayed a bit too far into
gauging the energy projections of others... by somehow turning down your
own thermostat in an effort to gain a clearer signal from outside sources.
i suggest that you set your mind more towards discovering and energizing
the things that provide you with joy, and be a bit less interested in what
other people might be doing, since it seems to be draining your vitality away.
