New hashimotos

I was diagnosed with Hashimotos a little over a month ago with a multinodular goiter. I was put on 50 mcg of synthroid and started feeling a little better until about 1 week ago. I now feel lifeless at times. I also have this new thing with my face tingling, like something tiny is crawling all over my face! I feel depressed and like I am going crazy because I cannot sleep! I start clinicals in nursing school in a week and dont think I will have the energy to withstand the long hours. Help, any suggestions?
