Hiya Julie. Are you still feeling cold or did it pass?
It's good you had the tests that rule out a medical reason. I'm no professional but I have had anxiety disorders a long time and a lot of experience and self taught knowledge! Grief, like anxiety is exhausting. I've had periods before where I'm cold for no reason, I had a long period of the opposite too, awful burning skin. The nervous system can take a big whack, and the adrenals too and this can mess with our 'thermometers'. When I'm worn out I get cold. Try not to worry, and if you're still feeling cold I'm sending you a gentle warm (hug) xxx
