I'd just like it say it's not always about getting older. I was diagnoses with an under active thyroid at 14 years old! I have always been thin. I get very frustrated with people saying I should be bigger in size. And I have no under laying "skinny" issues etc. And yes! I hate feeling cold! I can't ever de warm enough! Dry hair. Dry skin. Fatigue. It goes on. But bearable.
