Oh man! I love the cold, tbh. I kinda live in the desert :/ but it does snow here during the winter, unfourtunatly mainly in january and march. I had one white Christmas though!
Anyway, try and get some handwarmers. I have no idea how much they cost now, but they used to be generally cheap. They can really warm ya up!
Also, consider buying a heated blanket. They are so warrrrmmmm and comffffyyyyyy.
Thermostat. Turn up the heat! But if your dad or parent goes all crazy if you touch it, purchase a small space heater. Or consider going for a layered sweater look.
Merry Christmas!
