I can empathize. I have ALWAYS been cold in the winter for as long as I can remember. In high school, I would come home from sports practice after school and sit next to the heater while I did my homework. I'm the same way now.
Also, I have Reynaulds (it runs in my family) and it is THE WORST! Sometimes I'll be sitting in class and my fingers will just go numb, and there's nothing I can do to get feeling back! My boyfriend calls them ghost fingers because they are completely white. It's particularly annoying when my iPhone touch screen won't register my fingers because they're too cold
My only advice is bundle up! I got one of those long down jackets years ago from Jcrew, and it is a godsend in the winter. It might not be the chicest, but it is WARM!
