Bless your heart. I went through an almost identical process at 38 years old. I thought that I was dying. I told my best friend about my symptoms and we researched it together. It was truly an awful time, but it does get better. Thank goodness. I basically had to ride it out and try to stay comfortable by wearing layers, clothes that could "breathe" and by staying hydrated which helps to regulate your body temperature. I also keep (notice present tense) a small fan in my purse. Good luck. This too shall pass.
