First thing I would do is absolutely start dressing a lot more warmly. A lowered temp comes with its own series of problems. Dress as warmly as you can, drink hot drinks and take hot showers.

Also, people here will either advise you to raise carbs or raise fat. All this will tell you is how they eat. You need to listen to yourself. If your sleep has been effected and your temp is down, those are big signs that you're not going in the right direction.
Try the shift to Primal eating without aiming for specific macros and see how that affects you.
"I think the basic anti-aging diet is also the best diet for prevention and treatment of diabetes, scleroderma, and the various "connective tissue diseases." This would emphasize high protein, low unsaturated fats, low iron, and high antioxidant consumption, with a moderate or low starch consumption.
In practice, this means that a major part of the diet should be milk, cheese, eggs, shellfish, fruits and coconut oil, with vitamin E and salt as the safest supplements."
