well Lindsay, the cold is just the cold...its never fun at first! It looks to me like youre getting your diet down better, and often thyroid takes a little while to raise naturally...it fluctuates based on your intake over time...so you have to hammer home the point of good diet/calories for it to raise. The first couple days it was cold here I woke up freezing, but now maybe a couple weeks in my body has adjusted and I am able to handle it pretty, surprisingly, easy so far ( a stark turnaround from last year). Even tho the days are shorter, and its harder to get out of bed, make sure you still get in enough calories by day to keep sending your body the right signals. You could get a light thermal or robe that you can wear around the house and take on and off easily, or get a space heater for your bedroom and just turn it on before you sleep, then for like an hour when you wake up to get rolling. Ive been getting as much sun as I can recently, and ive found warming myself in the sun for an hour seems to carry all day...like I become much more resilient to the cold. I don't know if its a vit D or some kind of light benefit, but it definitely helps. Wishing the best...I pheer the winter now due to these past couple years...but this one doesn't seem so bad so far, so I think the fact ive been consistently getting a lot of T supporting nutrients and sunlight has helped. Theres always warm showers that can help shift you for a little while...and get a warm blanket for at night! (im sure you have!)
