Hi PL and welcome to the best Crohns forum out there. You will find alot of support and kindness here. When first diagnosed it is usually when you are the sickest. Once the doc finds the right treatment for you you will start feeling better, but remember sometimes that takes some time.
I think your always being cold is from the Hypothryoidism. I have a SIL and 2 nieces with it and they are always cold too. Sulfazine is a good starting med to help quiet things down. I am surprised he didn't put you on a short course of steroids with it to help quiet it down a little quicker.
Start a food diary and keep tract of foods that bother you. I follow a low residue diet all the time as that works best for me. Its generally a diet prescribed when you are flaring. Now that I am in remission I have modified it a little, but it still is the best diet for "me". Good luck!
